Using EES (or other) software, determine the work input to a multistage compressor for a given set of inlet and exit pressures for any number of stages. Assume that the pressure ratio across each stage is identical and the compression process is polytropic. List and plot the compressor work against the number of stages for P1 = 100 kPa, T1 = 25°C, P2 = 1000 kPa, and n = 1.35 for air. Based on this chart, can you justify using compressors with more than three stages?
