2. Air enters the compressor of a simple gas turbine at 14 psia, 520 R and a volumetric flow rate of 10,000 CFM (ft3/min). The isentropic efficiencies of the compressor and turbine are 83% and 87% respectively. The compressor pressure ratio is 14 and the temperature at the turbine inlet is 2500 R. Based on a air-standard analysis, calculate (a) the thermal efficiency, (b) the net power developed in HP, and (c) the rate of entropy production in the compressor and turbine, in hp/R.

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volume for a gas is much higher than the average volume for a liquid. d)-there is no difference.
