3.4 Refrigerant 134a enters a pipe with an inside diameter of 3.88 cm at 40 kPa, a quality of 0.15, and a velocity of 0.5 m/s. The refrigerant gains heat as it flows through the pipe and exits as a saturated vapor with a drop in pressure of 0.5 kPa. Determine the following:

a. Volumetric flow rate at the inlet of the pipe (L/s)

b. Mass flow rate of the refrigerant through the pipe (g/s)

c. Volumetric flow rate at the exit of the pipe (L/s)

d. Velocity of the refrigerant at the exit of the pipe (m/s)

e. Heat transfer rate to the refrigerant (kW) as it flows through the pipe
