Find the compression ratio
WebCompression ratio (R) – is the pressure ratio at discharge to suction pressure: R = Pd/Ps (where Pd and Ps are absolute). One stage compressor has only one R value. Two stage compressors have 3 R values. R = overall compression ratio R1 = first stage compression ratio R2 = second stage compression ratio. R = Pd/Ps R1 = Pi/P R2 = … WebDec 29, 2011 · The valves close and the piston moves up, compressing the 500 cc charge. If that charge is compressed into 50 cc, the compression ratio of the engine would be 10:1." Remember, under normal …
