Air_Compressor_Cycles

Air Compressor Cycles My PV diagram did not take the shape that I expected. The basic shape was what I expected, but where the 2nd stage starts I thought there would be more of a volume increase at V1 but there was in fact a slight decrease. Maybe this was because there was a slight time lapse before the computer recorded the reading. There were differences between the theoretical results and my observed readings. The efficiency is made worse if leaks occur past the valves or the piston. Ideally the processes between 1 and 4 and 2 to 3 are isothermal ie no temp change. It is hard to say if this was the case but from the graph it does seem to be overall. In reality the warm cylinder would cause a slight temperature rise over the induction from 4 to 1. The gas is restricted by the valves and they tend to move slightly so P1 was probably slightly less than P4.
