I would like to know if it is possible to get the actual/real compression ratio of a reciprocating compressor (one stage, one double-acting cylinder, size 8.5", rated capacity= 4775 Nm3/h, rated RPM = 370, Dresser-Rand), before starting up the machine?
Process people have specified compression ratio of 1.86 but I assume the real compression ratio is a function of the actual mechanical design from the manufacturer...right?
In addition I wanted to confirm that this compression ratio is independent of capacity. I mean is the compression ratio valid at 50/75 or 100% of rated capacity?
Thanks and regards
