<h3 id="_subsurface_appears_to_miscalculate_gas_consumption_and_sac">20.1. Subsurface appears to miscalculate gas consumption and SAC</h3>
<div class="paragraph" id="SAC_CALCULATION"><p><em>Question</em>: I dived with a 12.2 l tank, starting with 220 bar and ending
with 100 bar, and I calculate a different SAC compared what <em>Subsurface</em>
calculates. Is <em>Subsurface</em> miscalculating?</p></div>
<div class="paragraph"><p><em>Answer</em>: Not really. What happens is that <em>Subsurface</em> actually calculates
gas consumption differently - and better - than you expect. In particular,
it takes the incompressibility of the gas into account. Traditionally, Gas
consumption and SAC should be: <code>consumption = tank size x (start pressure -
end pressure)</code></p></div>
<div class="paragraph"><p>and that&#8217;s true for an ideal gas, and it&#8217;s what you get taught in dive
theory. But an "ideal gas" doesn&#8217;t actually exist, and real gases actually
don&#8217;t compress linearly with pressure. Also, you are missing the fact that
one atmosphere of pressure isn&#8217;t actually one bar. So the <strong>real</strong>
calculation is:</p></div>
<div class="paragraph"><p><code>consumption = (amount_of_air_at_beginning - amount_of_air_at_end)</code></p></div>
<div class="paragraph"><p>where the amount of air is <strong>not</strong> just "tank size times pressure in bar".
It&#8217;s a combination of: "take compressibility into account" (which is a
fairly small issue under 220 bar - you&#8217;ll see more differences when you do
high-pressure tanks with 300bar) and "convert bar to atm" (which is the
majority of your discrepancy). Remember: one ATM is ~1.013 bar, so without
the compressibility, your gas use is:</p></div>
<div class="paragraph"><p><code>12.2*((220-100)/1.013)</code></p></div>
<div class="paragraph"><p>which is about 1445, not 1464. So there was 19 l too much in your simple
calculation that ignored the difference between 1 bar and one ATM. The
compressibility does show up above 200 bar, and takes that 1445 down about
eight litres more, so you really did use only about 1437 l of air at surface
pressure.</p></div>
<div class="paragraph"><p>So be happy: your SAC really is better than your calculations indicated. Or
be sad: your cylinder contains less air than you thought it did. And as
mentioned, the "contains less air than you thought it did" really starts
becoming much more noticeable at high pressure. A 400 bar really does not
contain twice as much air as a 200 bar one. At lower pressures, air acts
pretty much like an ideal gas.</p></div>

<div class="paragraph"><p><em>Subsurface</em> ends up ignoring surface time for many things (average depth,
divetime, SAC, etc). <em>Question</em>: Why do dive durations in my dive computer
differ from that given by <em>Subsurface</em>?</p></div>
<div class="paragraph"><p><em>Answer</em>: For example, if you end up doing a weight check (deep enough to
trigger the "dive started") but then come back up and wait five minutes for
your buddies, your dive computer may say that your dive is 50 minutes long -
because you have fifty minutes worth of samples - but subsurface will say
it&#8217;s 45 minutes - because you were actually diving for 45 minutes. It&#8217;s
even more noticeable if you do things like divemastering the initial OW
dives, when you may stay in the water for a long time, but spend most of it
at the surface. And then you don&#8217;t want that to count as some kind of long
dive”.</p></div>

though my dive computer&#8217;s manual states that it records history of e.g. 999
dives.</p></div>
<div class="paragraph"><p><em>Answer</em>: Dive history is different than the dive profiles on the log. The
history only keeps track of the total number of dives and total amount of
time spent below surface. The logs, on the other hand, store the dive
profile, but they have limited amount of memory to do so. The exact amount
of dive profiles that can be stored on the device depend on sample interval
and duration of the dives. Once the memory is full the oldest dives get
overwritten with new dives. Thus we are only able to download the last 13,

<h3 id="S_APPENDIX_F">21.1. Subsurface appears to miscalculate gas consumption and SAC</h3>
<div class="paragraph" id="SAC_CALCULATION"><p><em>Question</em>: I dived with a 12.2 l tank, starting with 220 bar and ending
with 100 bar, and I calculate a different SAC compared what <em>Subsurface</em>
calculates. Is <em>Subsurface</em> miscalculating?</p></div>
<div class="paragraph"><p><em>Answer</em>: Not really. What happens is that <em>Subsurface</em> actually calculates
gas consumption differently - and better - than you expect. In particular,
it takes the incompressibility of the gas into account. Traditionally, Gas
consumption and SAC should be: <code>consumption = tank size x (start pressure -
end pressure)</code></p></div>
<div class="paragraph"><p>and that&#8217;s true for an ideal gas, and it&#8217;s what you get taught in dive
theory. But an "ideal gas" doesn&#8217;t actually exist, and real gases actually
don&#8217;t compress linearly with pressure. Also, you are missing the fact that
one atmosphere of pressure isn&#8217;t actually one bar. So the <strong>real</strong>
calculation is:</p></div>
<div class="paragraph"><p><code>consumption = (amount_of_air_at_beginning - amount_of_air_at_end)</code></p></div>
<div class="paragraph"><p>where the amount of air is <strong>not</strong> just "tank size times pressure in bar".
It&#8217;s a combination of: "take compressibility into account" (which is a
fairly small issue under 220 bar - you&#8217;ll see more differences when you do
high-pressure tanks with 300bar) and "convert bar to atm" (which is the
majority of your discrepancy). Remember: one ATM is ~1.013 bar, so without
the compressibility, your gas use is:</p></div>
<div class="paragraph"><p><code>12.2*((220-100)/1.013)</code></p></div>
<div class="paragraph"><p>which is about 1445, not 1464. So there was 19 l too much in your simple
calculation that ignored the difference between 1 bar and one ATM. The
compressibility does show up above 200 bar, and takes that 1445 down about
eight litres more, so you really did use only about 1437 l of air at surface
pressure.</p></div>
<div class="paragraph"><p>So be happy: your SAC really is better than your calculations indicated. Or
be sad: your cylinder contains less air than you thought it did. And as
mentioned, the "contains less air than you thought it did" really starts
becoming much more noticeable at high pressure. A 400 bar really does not
contain twice as much air as a 200 bar one. At lower pressures, air acts
pretty much like an ideal gas.</p></div>

<div class="paragraph"><p><em>Subsurface</em> ends up ignoring surface time for many things (average depth,
divetime, SAC, etc). <em>Question</em>: Why do dive durations in my dive computer
differ from that given by <em>Subsurface</em>?</p></div>
<div class="paragraph"><p><em>Answer</em>: For example, if you end up doing a weight check (deep enough to
trigger the "dive started") but then come back up and wait five minutes for
your buddies, your dive computer may say that your dive is 50 minutes long -
because you have fifty minutes worth of samples - but subsurface will say
it&#8217;s 45 minutes - because you were actually diving for 45 minutes. It&#8217;s
even more noticeable if you do things like divemastering the initial OW
dives, when you may stay in the water for a long time, but spend most of it
at the surface. And then you don&#8217;t want that to count as some kind of long
dive”.</p></div>

though my dive computer&#8217;s manual states that it records history of e.g. 999
dives.</p></div>
<div class="paragraph"><p><em>Answer</em>: Dive history is different than the dive profiles on the log. The
history only keeps track of the total number of dives and total amount of
time spent below surface. The logs, on the other hand, store the dive
profile, but they have limited amount of memory to do so. The exact amount
of dive profiles that can be stored on the device depend on sample interval
and duration of the dives. Once the memory is full the oldest dives get
overwritten with new dives. Thus we are only able to download the last 13,
30 or 199 dives.</p></div>

[[SAC_CALCULATION]]
'Question': I dived with a 12.2 l tank, starting with 220 bar and ending

_Subsurface_ provides a mechanism to create or modify templates for printing
dive logs in order to produce customised printouts of dive logs. Templates,
written in HTML as well as a simple Grantlee instruction set, are rendered
to the print device by _Subsurface_.
'Answer': Not really. What happens is that _Subsurface_ actually calculates
gas consumption differently - and better - than you expect. In particular,
it takes the incompressibility of the gas into account. Traditionally, Gas
consumption and SAC should be: +consumption = tank size x (start pressure -
end pressure)+
Templates are accessed using the print dialogue (see image *B* below).
and that's true for an ideal gas, and it's what you get taught in dive
theory. But an "ideal gas" doesn't actually exist, and real gases actually
don't compress linearly with pressure. Also, you are missing the fact that
one atmosphere of pressure isn't actually one bar. So the *real*
calculation is:

where the amount of air is *not* just "tank size times pressure in bar".
It's a combination of: "take compressibility into account" (which is a
fairly small issue under 220 bar - you'll see more differences when you do
high-pressure tanks with 300bar) and "convert bar to atm" (which is the
majority of your discrepancy). Remember: one ATM is ~1.013 bar, so without
the compressibility, your gas use is:
The Edit Panel comprises three tabs:
+12.2*((220-100)/1.013)+
image::images/Template1_f22.jpg["FIGURE: template edit dialogue", align="center"]
which is about 1445, not 1464. So there was 19 l too much in your simple
calculation that ignored the difference between 1 bar and one ATM. The
compressibility does show up above 200 bar, and takes that 1445 down about
eight litres more, so you really did use only about 1437 l of air at surface
pressure.
1) The _Style_ tab (image *A* above) controls the font, line spacing and colour
template used for printing the dive log. The style attributes are
editable. Choose one of the four colour palets used for colour printing.
So be happy: your SAC really is better than your calculations indicated. Or
be sad: your cylinder contains less air than you thought it did. And as
mentioned, the "contains less air than you thought it did" really starts
becoming much more noticeable at high pressure. A 400 bar really does not
contain twice as much air as a 200 bar one. At lower pressures, air acts
pretty much like an ideal gas.
2) The _Colors_ tab (image *B* above) allows editing the colours used for
printing the dive log. The colours are highly customisable: the _Edit_
buttons in the _Colors_ tab allows choosing abritrary colours for different
components of the dive log printout.

3) The _Template_ tab of the Edit Panel (see image below) allows creating a
template using HTML as well as a few Grantlee programming
primitives. Grantlee provides the ability to create and format HTML code in
a highly simple but efficient way (see below). The HTML of the template can
be edited and saved. The saved template is stored in the same directory as
the dive being processed. By default, a _Custom_ template is a skeleton with
no specific print instructions. The informastion being printed needs to be
specified and formatted in the by replacing the section marked with: "<!--
Template must be filled -->". Writing HTML code with Grantlee instructions
allows unlimited freedom in determining what is printed an in which way it
should be rendered.
_Subsurface_ ends up ignoring surface time for many things (average depth,
divetime, SAC, etc). 'Question': Why do dive durations in my dive computer
differ from that given by _Subsurface_?
image::images/Template2_f22.jpg["FIGURE:Template tab", align="center"]
'Answer': For example, if you end up doing a weight check (deep enough to
trigger the "dive started") but then come back up and wait five minutes for
your buddies, your dive computer may say that your dive is 50 minutes long -
because you have fifty minutes worth of samples - but subsurface will say
it's 45 minutes - because you were actually diving for 45 minutes. It's
even more noticeable if you do things like divemastering the initial OW
dives, when you may stay in the water for a long time, but spend most of it
at the surface. And then you don't want that to count as some kind of long
dive”.
=== Some dive profiles are missing from the download
[[DC_HISTORY]]
'Question': I cannot download all my dives, only the most recent ones even
though my dive computer's manual states that it records history of e.g. 999
dives.
'Answer': Dive history is different than the dive profiles on the log. The
history only keeps track of the total number of dives and total amount of
time spent below surface. The logs, on the other hand, store the dive
profile, but they have limited amount of memory to do so. The exact amount
of dive profiles that can be stored on the device depend on sample interval
and duration of the dives. Once the memory is full the oldest dives get
overwritten with new dives. Thus we are only able to download the last 13,
30 or 199 dives.
If you have downloaded your dives to different dive logging software before
they were overwritten, there is a high change that Subsurface can import
these. However, if the logs are only on your dive computer, they cannot be
salvaged after being over written by new dives.
== APPENDIX F: Write a custom printing template
_Subsurface_ provides a customizable printing support which is based on
templates that are transformed by the _Grantlee_ backend to correct _HTML_
syntax, The _HTML_ output is then rendered by _Subsurface_.
One can adapt any of the existing templates and save it to the dive log
directory. The standard templates (e.g. One dive, Six dives, Table) can be
modified in this way.
To write a custom template the following elements must exist so that the
template will be correctly handled and rendered.

IMPORTANT: All CSS units should be in relative lengths only, to support printing on any
page size.

=== Subsurface appears to miscalculate gas consumption and SAC
[[SAC_CALCULATION]]
'Question': I dived with a 12.2 l tank, starting with 220 bar and ending
with 100 bar, and I calculate a different SAC compared what _Subsurface_
calculates. Is _Subsurface_ miscalculating?
'Answer': Not really. What happens is that _Subsurface_ actually calculates
gas consumption differently - and better - than you expect. In particular,
it takes the incompressibility of the gas into account. Traditionally, Gas
consumption and SAC should be: +consumption = tank size x (start pressure -
end pressure)+
and that's true for an ideal gas, and it's what you get taught in dive
theory. But an "ideal gas" doesn't actually exist, and real gases actually
don't compress linearly with pressure. Also, you are missing the fact that
one atmosphere of pressure isn't actually one bar. So the *real*
calculation is:
+consumption = (amount_of_air_at_beginning - amount_of_air_at_end)+
where the amount of air is *not* just "tank size times pressure in bar".
It's a combination of: "take compressibility into account" (which is a
fairly small issue under 220 bar - you'll see more differences when you do
high-pressure tanks with 300bar) and "convert bar to atm" (which is the
majority of your discrepancy). Remember: one ATM is ~1.013 bar, so without
the compressibility, your gas use is:
+12.2*((220-100)/1.013)+
which is about 1445, not 1464. So there was 19 l too much in your simple
calculation that ignored the difference between 1 bar and one ATM. The
compressibility does show up above 200 bar, and takes that 1445 down about
eight litres more, so you really did use only about 1437 l of air at surface
pressure.
So be happy: your SAC really is better than your calculations indicated. Or
be sad: your cylinder contains less air than you thought it did. And as
mentioned, the "contains less air than you thought it did" really starts
becoming much more noticeable at high pressure. A 400 bar really does not
contain twice as much air as a 200 bar one. At lower pressures, air acts
pretty much like an ideal gas.
