Air enters the first stage of a compressor operating at steady state at 96 kPa, 16C with a volumetric flow rate of 162 m/min. The compression occurs in two stages, with each stage being a polytropic process with n=1.27. The air is cooled to 27C between the compressor stages by an intercooler (a heat exchanger) operating at a constant pressure of 310 kPa. Air exits the second stage compressor at IMPa. Assuming ideal gas, determine, in kW, a. The power and heat transfer rate for each compressor stage b. The heat transfer rate for the intercooler Compressor stage 1 Intercooler mmm Qout Compressor stage 2 Info: The net work output of a gas turbine can be increased by reducing the compressor work input. This can be accomplished by means of multistage compression with intercooling.
