Ten kg/s of saturated liquid R -134 at 12 bar passes through a value as it enters an insulated central volume. The value reduces the pressure to 2.8 bar. Find the mass flow rate of vapor that is leaving the central volume (kg/s)

Solution

The process is equal to throttling process which is a isenthalpic process

Hence the mass flow rate won\'t change

Initial mass flow rate = final mass flow rate = 10kg/s
