Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am interested in finding out the electric power output from a compressed air system. i see that there is a formula for calc. it with

the amount of compressed air required to generate about 1 W with a pressure of 1 bar is given by

Compressed air(cu.mm/s) = (1000 N-mm/s) / (0.1 N/sq.mm)

But since air is compressible fluid , I think we need to consider temp and pressure ratios. But what I am also wanting to know is if there is a general rule like A cu.m/min of compressed air at 100 psi gives B watts of power
