Air is compressed in a steady-flow compressor via a polytropic process from 15 psia and 60 degree F (State 1) to 75 psia and 294 degree F (State 2). Calculate the specific work (Btu/Ibm) for the compressor. Determine the specific heat transfer (Btu/Ibm) for the compressor. Show the compression process on P-v and T-s diagrams. What do the areas under the process curve on the P-v and T-s diagram represent?
