Question: A enters a diffuser steadily as saturated vapor at 800 kPa with a velocity of 120 m/s, and it leaves at 900 kPa and 40C.

A enters a diffuser steadily as saturated vapor at 800 kPa with a velocity of 120 m/s, and it leaves at 900 kPa and 40°C. The refrigerant is gaining heat at a rate of2 kJ/s as it passes through the diffuser. If the exit area is 80 percent greater than the inlet area, determine
(a) The exit velocity and
(b) The mass flow rate of the refrigerant.
