Argon gas enters an adiabatic compressor at 100 kPa and 25oC with a velocity of 20 m/s

Question:

Argon gas enters an adiabatic compressor at 100 kPa and 25oC with a velocity of 20 m/s and exits at 1 MPa, 550oC and 100 m/s. The inlet area of the compressor is 75 cm2. Assuming the surroundings to be at 100 kPa and 25oC, determine
(a) The internal entropy generation rate by this device.
(b) The external entropy generation in the immediate surroundings.
(c) The entropy generation in the system's universe.
