Air enters a compressor operating at steady state at 14 lbf/in?, 60F, with a volumetric flow rate of 6400 ft3/min. The compression occurs in two stages, with each stage being a polytropic process with n = 1.27. The air is cooled to 80F between the stages by an intercooler operating at 45 lbf/in2. Air exits the compressor at 150 lbf/in?. Step 1 Your answer is correct. Determine the magnitude of the total power required by the compressor, in Btu/min. Wc = 45466.44 Btu/min Determine the magnitude of the total heat transfer rate for both compressor stages, in Btu/min. ec II i Btu/min
