Welcome to PF, sorry about the delay.
Maybe you are referring to the ratio or factor of 1.4 in air compressor efficiency.
The air is compressed which also heats it, then passed to an air receiver chamber where it cools, so the pressure drops slightly. That cooling represents a waste of input energy.
See; http://en.wikipedia.org/wiki/Heat_capacity_ratio
Then ask more specific questions as needed.
