Air steadily enters a compressor at 96 kpa and 27c (state 1) with a volumetric flow rate of 26.91 m3 /min. air is compressed to 230 kpa and 127c (state 2). air leaving the compressor enters a counter-flow heat exchanger and is cooled to 77c (state 3) with negligible pressure drop. a separate cooling water stream enters the heat exchanger at 1 bar and 25c (state 4) and exits at 1 bar and 40c (state 5). (a) calculate the compressor power (kw). (b) determine the isentropic efficiency (%) of the compressor. (c) find the mass flow rate (kg/s) of the cooling water considering cooling water stream to be incompressible with a specific heat of 4.18 kj/kg-k. (d) calculate the rate of entropy production (kw/k) for the comp
