Air is compressed steadily by a 5 kW compressor from 100 kPa and 17?C to

600 kPa and 167?C at a rate of 1.6 kg/min. During this process, some heat transfer takes

place between the compressor and the surrounding medium at 17C.

Determine

a. the rate of heat transfer from the compressor.

b. the rate of change in entropy in the control volume during this process.

c. the difference in the entropy rate between inflow and outflow.

d. the change in entropy of the surroundings during this process.

e. the change in entropy of the world during this process. ( 0.815 W/K)

f. Sketch the process on a T-s diagram that includes the constant pressure curves

through the initial and final states.
