We have a reciprocating compressor operating at 800 rpm. Suction pressure and discharge pressure are held constant by other systems that have nothing to do with the compressor. We increase the speed from 800 to 840 rpm (a 5% increase).
What is the change in flow rate through the compressor Flow increases by (840/800) or 1.05, or 5% increase?
What is the change in pressure rise through the compressor?
What is the change in power that must be delivered to the compressor?
