Refrigerant 134a enters an insulated diffuser as a saturated vapor at 60oF with a velocity of 1000 ft/s. The inlet area is 1.4 in2. At the exit, the pressure is 400 lbf/in2 and the velocity is negligible. The diffuser operates at steady state and potential energy effects can be neglected. Determine the mass flow rate, in lb/s, and the exit temperature, in oF.
