Refrigerant-134a enters a 28-cm-diameter pipe steadily at 200 kPa and 20°C with a velocity of 5.4 m/s. The refrigerant gains heat as it flows and leaves the pipe at 180 kPa and 40°C.
(a) Determine the volume flow rate of the refrigerant at the inlet.
(b) the mass flow rate of the refrigerant.
(c) the velocity and volume flow rate at the exit.
