Question

If an oxygen bottle delivers 7 cubic feet of oxygen in 4 minutes at 27,000 feet and -65 degrees F. How much will the system deliver in 13 minutes

Answer 1

answer: 22.75 cubic feet of oxygen

assuming that the altitude and temperature is the same,

the ratio of cubic feet of oxygen : minutes is 7 : 4,

we multiply by 13...

91 : 52

then we divide by 4...

22.75 : 13

the system will deliver 22.75 cubic feet of oxygen.
