Re: [PSUBS-MAILIST] Re: Emergency life support



I diffidently plan of having a scrubber and would prefer to purchase a factory made one but after pricing them threw Divex and some of the other retailers, I may end up building my own. We used to have some nice ones in our saturation diving bells but they may have been 110V powered.

Rick,
 
Don't forget about planning for adequate CO2 scrubber capacity and function which seems to be more difficult than O2 especially considering emergency power or no power.

I am building a K-350 and am trying to figure out how many cubic feet of 02 I will need to have on board to support 2 people for 72 hours. My hull ID is 36" and I am using a length of 7.5 feet long to include the end caps.
The conning tower is 23" ID X 18" to include the hatch. I came up with 57.32 cu ft. Is this correct and if so, can someone tell me how many cu ft of 02 I would need to carry based on the average aspiration rate of two people?
 
Thanks
