Refrigerant 134a enters the evaporator of a refrigeration system operating at steady state at -4o C and quality of 20% at a velocity of 7 m/s. At the exit, the refrigerant is a saturated vapor at a temperature of -4o C. The evaporator flor channel has constant diameter. If the mass flow rate of the entering refrigerant is 0.1 kg/s, determine
