Air is compressed steadily by a compressor from 100 kPa and 27°C to 800 kPa and 290°C.The mass flow rate of the air is 15 kg/min. During the process, the heat is lost from thecompressor at a rate of 15 kW to the surrounding at 27°C. Assume air to be an ideal gas andthe changes in kinetic and potential energies can be neglected. e) To prevent the heat loss from the compressor to the surrounding, the compressor iswell insulated. Assuming the exit temperature of the air remain the same, find thenew power required by the compressor, kW.f) Does the process as in (e) satisfy or violate the second law of thermodynamics.Show the calculation to support your answer.

As I have solved previous parts of this question so I am attaching those answers for reference.

e) To prevent the heat loss from the compressor to the surrounding, the compressor is well insulated. Assuming the exit temperature of the air remain the same, find the new power required by the compressor, kW. f) Does the process as in (e) satisfy or violate the second law of thermodynamics. Show the calculation to support your answer.
