Argon gas enters an adiabatic compressor at 100 kPa, 25oC, 20 m/s and exits at 1 MPa,

Question:

Argon gas enters an adiabatic compressor at 100 kPa, 25oC, 20 m/s and exits at 1 MPa, 550oC, 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 reversible power,
(b) Irreversibility for this device and
(c) The exegetic efficiency.
(d) What-if Scenario: What would the answers be if the compressor lost 5 kW of heat to the atmosphere due to poor insulation?
