- In a compressor, air enters at 100 kPa and 20 ° C and leaves the compressor at 1200 kPa and 300 ° C. Mass flow rate of the air is 0.65 kg / s and 8 kw heat load is discharged from the fins on the compressor surface to the environment at 20 ° C. Assuming the specific heat as constant, calculate (a) the power input to the compressor, (b) the thermal efficiency, and (c) the amount of entropy produced during this process. 300°C 1.2 MPа mprocco

- In a compressor, air enters at 100 kPa and 20 ° C and leaves the compressor at
1200 kPa and 300 ° C. Mass flow rate of the air is 0.65 kg / s and 8 kW heat
load is discharged from the fins on the compressor surface to the environment at
20 ° C. Assuming the specific heat as constant, calculate (a) the power input to
the compressor, (b) the thermal efficiency, and (c) the amount of entropy
produced during this process.
