Argon gas enters an adiabatic compressor under steady flow conditions at 12o kpa and 30 C with a velocity of 20 m/s and exits at 1.2 Mpa, 530 C and 80 m/s. The inlet area is 130m^2. Assuming the surroundings to be at 25 C, determine The reversible power input in kW and the entropy generation in Kw/k and irreversibility in kW.
