SCR poll

[landlocked]

Recent posts have dealt with specific gas management issuses with the intent of helping recreatioal divers better understand some of the issues that are involved. It has also been claimed that some of these issues are beyond the skills of truly recreational divers. So lets pick one and see. Do recreational divers know what thier SCR is? Mine varies rather widely.

Not familiar with the anacronym. My SAC varies considerably, based upon workload and temperature.

If talking about "surface consumption rate," yes, I know what it typically is -- and more importantly I know its range for a variety of activity levels.

Is SCR just another term for SAC? If so, yes, I know what it is.

 

[SeaHunt]

No, I haven't a clue. How about a little info on how to determine it...

 

[cpalerm]

SCR = Surface Consumption Rate
SAC = Surface Air Consumption

I guess it's just a matter of which you like best (being an engineer I prefer SCR)...

If you don't know how to calculate it/use it, here is a link that could be useful:

My SCR varies widely, however my rate is usually alot longer than my wifes and usually alot longer than others that are diving on the same boat. My air can last over two hours on one 80 at shallow depth, such as the reefs in Florida, like Sombrero or Pennecamp. I guess that I can't give you a specific but, I think most of the SCR comes down to being comfortable in the water.

Dive Safe,

I've got an SLR.

It's 35 mm!

My respiratory minute volume is . . . variable. (I eat physiology textbooks for breakfast!

Between 14 and 20 litres per min.
