refrigerant 134a enters the evaporator of a refrigeration system operating at steady state at -12°C and a quality of 20% at a velocity of 7 m/s. At the exit, the refrigerant is a saturated vapor at -12°C. The evaporator flow channel has constant diameter of 1.7cm.
Determine the mass flow rate of the refrigerant in kg/s
Determine the velocity at the exit in m/s
