Hi, Can anyone help me with a personal project I am working on? I wish to compress air in a container up to 100psi. I'm making a small single cylinder compressor to achieve that. The container is small, approx 0.05 cubic feet. I'm trying to work out how many strokes of the compressor it will take. I know the swept volume of the compressor. Am I right to assume that the number of strokes required against pressure is not linear? I have researched Boyles Law etc but I'm just getting confused! How do I work out how many strokes to get from say, 50 psi to 60 psi? Any help would be much appreciated.
