Estimate the work necessary to compress the air in an
air-compressor cylinder from a pressure of 100 kPa to 2000 kPa. The
initial volume is 1000
.
An isothermal process is to be assumed.
Homework Answers
PV = RT ====> RT = PV = (100000*1000*10^-6) = 100
Now work done = RT*ln(P1/P2) = 100*ln(100/2000) = -300 J (-ve sign for compression)

two stage compressor with intercooling between the stages is used to compress air from 1 bar and 15C to 9 bar in a Gas-Turbine cycle . The high pressure turbine drives the compressor whereas low pressure turbine is coupled with an electrical generator. The compressor and turbine efficiencies are 85%; 75%, respectively. Heat is added to the compressed air after leaving the compressor till its temperature reaches 900C. The air then expands in HPT to an intermediate pressure and reheat...
