Two streams of R-134a flow into a non-insulated diffuser. Stream 1 enters at a pressure of 2 bar and 20?C (State

1) with a velocity of 200 m/s through an area of 0.1 m2 while stream 2 enters as saturated vapor at 2 bar (State

2) with a velocity of 100 m/s through an area of 0.05 m2. R-134a exits the diffuser at 2.8 bar and 40?C (State 3) with a velocity of 20 m/s.

(a) Calculate mass flow rate (kg/s) of the refrigerant at the exit of the diffuser.

(b) Find area (m2) at the exit of the diffuser.
