Design a system to remove the respiration carbon dioxide from inside a submarine and replace it with oxygen. The air volume of the submarine is 1000. m3 , and the crew can generate a maximum of 1.30 × 10-3 m3 /s of CO2.
The submarine must be able to achieve a depth of 300. m. Assume the air mixture enters your system at 30.0°C and exits at 20.0°C.
Maintain the oxygen partial pressure at all times in your mixture equal to that in atmospheric air at 0.1013 MPa and 20.0°C.
