Air at 80 kPa and 127 degrees Celsius enters an adiabatic diffuser steadily at a rate of 6000 kg/hr and leaves at 100 kPa. The velocity of the air stream decreases from 230 m/s to 30 m/s as it passes through the diffuser. Find the following:
(A) Calculate the inlet area of the diffuser
(B) Determine the enthalpy of air at the exit
(C) Determine the temperature of air at the exit
