Refrigerant-134a enters a 28-cm-diameter pipe steadily at 200 kPa and 20°C with a velocity of 5.5 m/s. The refrigerant gains heat as it flows and leaves the pipe at 180 kPa and 40°C. The specific volumes of R-134a at the inlet and exit are 0.1142 m3/kg and 0.1374 m3/kg. Determine (a) the volume flow rate of the refrigerant at the inlet, (b) the mass flow rate of the refrigerant, and (c) the velocity and volume flow rate at the exit.
