Refrigerant 134a enters a tube in the evaporator of a refrigeration system at 132.73 kPa and a quality of 0.15 at a velocity of 0.5 m/s. The R134a exits the tube as a saturated vapor at −21°C. The tube has an inside diameter of 3.88 cm. Determine the following,

a. The pressure drop of the R134a as it flows through the tube (kPa)

b. The volumetric flow rate at the inlet of the tube (L/s)

c. The mass flow rate of the refrigerant through the tube (g/s)

d. The volumetric flow rate at the exit of the tube (L/s)

e. The velocity of the refrigerant at the exit of the tube (m/s)

f. The heat transfer rate to the refrigerant (kW) as it flows through the tube
