3. Air with 100 kPa, 300 K flows into the insulating compressor
with a flow rate of 2 kg/s, compressed to 1000 kPa and then
discharged to the exit. The back entropy efficiency of the
compressor is 82%. The gas constant of the ideal gas is the air,
and the meanness of the air is , The mean ratio is k=1.4. Ignore
kinetic energy and position energy.
1) Draw a schematic diagram and a T-s plot of the compressor.
2) Obtain the air temperature and the input (kW) of the compressor
at the exit.
3) Obtain the amount of entropy production from the compressor.
