A two-stage air compressor operates at steady state, compressing 10 m^3/min of air from 100kPa, 300 K to 1200 kPa. An intercooler between the two stages cools the air to 300 K at a constant pressure of 350 kPa. The compression processes are isentropic. Assume that specific heats vary with temperature. Consider the following: 1. Determine the power (kW) required to run the compressor. 2. Calculate the power (kW) required for isentropic compression from the same inlet state to the same final pressure in a single stage.
