Air enters a compressor operating at steady state at t1 = 320 k, p1= 2 bar with a velocity of 80 m/s. at the exit, t2 = 550 k, p2=10 bar and the velocity is 180 m/s. the air can be modeled as an ideal gas with cp 1.01 kj/kg k. stray heat transfer can be ignored. let to= 300 k, po= 1 bar.

determine, in kj per kg of air flowing:

a. the magnitude of the power required by the compressor.
b. the rate of exergy destruction within the compressor.
