Question: refrigerant r134a enters an insulated diffuser as a saturated vapor...

Question details
Refrigerant R134a enters an insulated diffuser as a saturated vapor of 27 deg C with a velocity of 440 m/s. At the exit, the temperature is 138 deg C and the velocity is negligible. The diffuser operates at steady-state and potential energy effects can be ignored. Determine the exit pressure, in kpa.
