Refrigerant-134a enters a 28-cm diameter

Refrigerant-134a enters a 28-cm diameter pipe steadily at 200 kPa and 20째C with a velocity of 5 m/s. The refrigerant gains heat as it flows and leaves the pipe at 180 kPa and 40째C. 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.
