Regeneration, Reheat, and Compression with Intercooling Air enters a compressor operating...

Regeneration, Reheat, and Compression with Intercooling Air enters a compressor operating at steady state at 14 lbf/in.2, 60°F, with a volumetric flow rate of 6000 ft3/min. The compression occurs in two stages, with each stage being a polytropic process with n = 1.27 The air is cooled to 80°F between the stages by an intercooler operating at 45 lbf/in.2 Air exits the compressor at 150 lbf/in.2 Determine, in Btu per min

(a) the power and heat transfer rate for each compressor stage.


(b) the heat transfer rate for the intercooler.
