4.18 Refrigerant 134a enters the evaporator of a refrigeration system operating at steady state at -4°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 -4°C. The evaporator flow channel has constant diameter. If the mass flow rate of the entering refrigerant is 0.1 kg/s, determine (a) the diameter of the evaporator flow channel, in cm. (b) the velocity at the exit, in m/s. __________________________________________________________________________________________ Textbooks: _____ Fundamentals of Engineering Thermodynamics 8th Edition (Wiley): Moran, M.
