Yes, but I'm too lazy to dig out my thermo book and find it. There are actually three equations. One for compressing air at constant temperature (isothermal), one for compressing air without taking any heat out (adiabatic), and the third for real world situations where only some of the heat of compression is taken out during compression (I forget the name).
And a real world rule of thumb: In industrial compressed air systems, it takes four hp of air compressor to run one hp of air motor.
