cubic feet

[karisegraves]

I was just wondering in terms of cubic ft.? About how many cubic ft. of air can the lungs hold and at what psi?

Anyone knows about this?

There is a whole range of lung volume, depending on factors such as age, sex, and your own genes. Let's say 5 liters is an average volume.
Under normal conditions, air pressure in the lungs is the same as ambient pressure, let's say one atmosphere if you are at sea level.

1L=0.035314 cubic feet, and one atmosphere = 14.696 PSI.

So your answer is about 0.15 cubic feet and 15 PSI. Don't plan anything dangerous or life-critical based on these numbers.
