physics

A reciprocating compressor is a device that compresses air by a back-and-forth straight-line motion, like a piston in a cylinder. Consider a reciprocating compressor running at 150 rpm. During a compression stroke, 1.30 mol of air is compressed. The initial temperature of the air is 390 K, the engine of the compressor is supplying 8.4 kW of power to compress the air, and heat is being removed at the rate of 1.9 kW. Calculate the temperature change per compression stroke.
