Gas you used.Hard Conditions: Decent to a depth of 10m look at your computer and SPG. start to swim as fast as possible for 10min and check how much gas you used.Take notes how much Gas you used in ether way on 10m of depth!You start on 10m of depth with 180 bar after 10min you check the pressure again and you have 150 bar left in your S-80 tank whats your SAC rate?30 bar * 11.1 L (Tank Size) = 333 L / 2 bar (ambient Pressure at 10m) = 166.5 L / 10 min = 16.65 L / Min. (SAC)Now we know how many litres of Gas we are consuming on 10 m of depth in 10 min. and like this, we can figure out what kind of Gas Supply we need to have for our Dive-plan.Also we can use this to determine an average SAC Rate for example:I dived 60 min consumed 150 bar on an average depth of 12m.150 bar * 11.1 L (Tank Size) = 1665 L / 2,2 bar (ambient Pressure at 12 m) = 756,81 L / 60 min = 12.61 L / Min. average (SAC)Calculate a decompression dive plan (ohne die CNS Calculations)GASPlanned vol.With ReserveN 323160 L4740 LBottom Gas *1,5N 99320 L640 LDeco Gas * 2,0DepthTimeRun TimeSACConv F.

Why we should know our Gas Consumption?We as trained and certified SCUBA Divers learn already at the Open Water Diver Course, to take a close look at our Gas Supply. But are we really aware of our Gas Consumption?We learn at our entry-level courses the different Markings of the SCUBA Tank:DOT Number and MaterialManufactorySerialnumberHydrostatic TestTank SizeAlso, we learn to determine the remaining Tank Pressure by using the Pressure Gauge (SPG) or AIR integrated Dive-computer. Skills like Low on, Out of Air and CESA are helping us to understand the importance of the Breathing Equipment. And in the very unlikely event of an Out of AIR situation to react the correct way and safely accent to the surface.But do we know about our AIR Consumption in-depth? Most certified divers never really heard about SAC Rate and how to Calculate it.The Gas-Consumption Calculations coming to effect if you really plan your dive with your dive buddy yourself. And you would like to make sure from the beginning that your gas supply is sufficient for your planned dives. In technical diving, these calculations are there for a long time and standard in the Decompression Diver course. But also as a Sports Diver, it is a benefit if you know about your SAC rate. How to determine your Gas ConsumptionKnow the size of your SCUBA Tank: S-80 Aluminium = 11.1 LNormal Conditions: Decent to a depth of 10m look at your computer and SPG. start to swim normally for 10min and check how much

Was down, cognitive functions were not restored for some hours!) Let’s double that up to 30 minutes – seems fair for us mere mortals. You will probably be well north of 30 min while on stops as ceilings are pretty much guaranteed to start before the 30 mins is up (individuals sac rates can and will vary but variations upwards from 45 lpm are a much safer bet and substantially more likely than down.)How can we plan for this? Well, an alternate is to plan for 30 minutes of breathable gas at any depth of the dive at 45 lpm + (maybe 60 min?), and the rest of the gas needs at a more normal sac rate (minimum of 30 lpm). This higher gas volume can then be bottom gas and maybe a possible combination of bottom and intermediate gas for very deep dives. The joy of this being high volume and maybe multi-cylinder is that it will also be high helium content, so neutral or floaty and easy to have on a leash with little effort to haul around once in the water.What if you have to bail on deco I hear… well good news in many waysYou will already be significantly shallowerYour bottom gas is probably breathable, and your intermediate gas is definitely breathable at all stops except maybe 6m or 9m for very deep dives. The impact on switching to intermediate or bottom gas even if already on stops will be negligible on remaining deco time, as in TTS will stay static while on a less than ideal but thank (insert your preferred deity or expletive) I have something to breathe gas. Even switching to bottom gas will only lead to significant increases if still deeper than 45m and you will be ascending at a fair rate if so. You will probably be with your teammates as you will have planned to ascend as a team and nothing went wrong so far, so their gas is also available if you screwed your calculations up (take a credit card if you want to access my bailout gas)You are.

Litres per minute at an average depth of 20mCompensate for depth(Depth / 10) +1 (20m/10) + 1 = 3 Therefore:60 litres per minute / 3 = 20 litres per minute SAC rateEasy, no? Why calculate SAC rate? I was in the dive shop one afternoon and I mentioned SAC in conversation. I received a look from another diver in the shop, along with the comment;“Oh … you’re one of those divers…” I don’t really know what one of “those divers” is, but, yes; yes I am.SAC rate can be so easily calculated!I calculate my SAC rate on every dive; I find it extremely useful. If your SAC rate is elevated, it can help a diver determine factors during the dive that may have created discomfort, stress or exertion. Knowing how much air a diver uses is also paramount in planning a dive. EXAMPLE of my dive planning using SAC rateMy SAC rate is 15, the local wreck dive is 16m average depth, and I plan to finish the dive with 50 bar in my twin 7’s, currently filled to 230 bar. 230 bar – 50 bar reserve = 180 bar useable gas180 bar x 14 litres (twin 7l tanks) = 2520 litresAir consumption at depth: (16m / 10) + 1 = 2.6 ATA15 (SAC rate) x 2.6 = 39 (litres per minute at 16m) 2520 / 39 = 64 minutes This figure can help determine if it is a decompression dive, or if I want to dive longer, consider a bigger twinset etc. I also know that every 10 minutes I should be using 390 litres, which equals 30 bar (ish). 39 per min x 10 = 390 litres390 litres / 14 litres (twin 7 tanks) = 27.85 bar During the dive I can check if I am using my projected air consumption. If I am using more it may be an indication something is affecting the dive and alter the dive plan accordingly. FACTORS THAT AFFECT SAC Size of the diver; smaller divers have smaller lungs, therefore a lower SACWomen generally have a lower SAC rate than menSmokers tend to have a higher SACBMI. The larger diver requires more O2 than skinny folk, hence a higher SACHealthy divers use less airHow relaxed a diver is during the dive; stress or anxiety increases SACExertion; fining in strong current will make a diver out of breath and increase SACStreamlining kit and reducing drag in the water can keep SAC downFlat trim also reduces drag and effects SACGood buoyancy will help SAC, as a diver isn’t constantly inflating and deflating BCD and working to maintain depthDiving in cold conditions can increase SACBadly maintained gear; any leaks, no matter how small, will have

Calculating SAC Rate and RMV - ScubaBoard

An effect on SAC as extra air is being used CONCLUSIONI love all things scuba, and I enjoy calculating my SAC rate as it is another aspect of the dive that continues, even after the underwater bit is over. I find it interesting to watch my personal SAC rate vary from dive to dive depending on the conditions. In Ireland it is usually 15 l/m on my local site. When I conducted a technical dive on a site I didn’t know it increased to 17 l/min. I was able to determine the increase was due to the anxiety of diving a new site, diving with a new buddy, and falling from a rhib which I wasn’t entirely comfortable kitting up on. As a result when I plan my technical dives I used a SAC rate higher than my usual, to compensate for any anxiety I may have on the day. When I dive in warm water it can plummet to 12 l/m. This is because I’m in a single tank, wet suit, crystal clear water and not freezing my nads off. Wifebuddy and I ARE DIVER enjoying low SAC rate in SharmWhat’s your SAC rate? Include some details so we can compare scenarios. For those who don’t know your SAC rate, do it next dive and post here with the result. It’s all part of the fun, and there’s no wrong answer!
