2 -- 318 cubic feet (equal volume) compressed air tanks are side by side.

One is full at 312 psi and the other is at atmospheric pressure.

I know that if I open up a valve between the 2 that I am able to transfer half of the compressed air and lose some energy to friction/heat.

How much energy will it take me to move the last half of compressed air over?

312 psi / 2 = 156 psi x .9 = 140 psi (assuming 10% lost in friction/heat)

How much energy to compress/move the 318 cubic feet of air at 140 psi over to the other tank?

Will cooling help to reduce the energy loss?
