Answer the other probem (NOT 1C5) use 1C5 as a reference 1.C.5. The refrigerant in an evaporator goes through phase change at a constant temperatureof −30◦C. The rate of vaporization of the refrigerant is 0.15 kg/s. The latent heat of vaporization ofthe refrigerant is 412.1 kJ/kg. Air enters the evaporator at mass flow rate 1.1 kg/s with a temperatureof 45◦C. Assume air has a constant specific heat of 1007 J/kg·K. What is the effectiveness of this heatexchanger? It was found that the convection coefficient of air in the evaporator described in Example 1C.5 is350 W/m2·K, and the heat transfer surface area is 5.1 m2. What is the average convection coefficientof the refrigerant under these conditions? (Note: As the refrigerant is evaporating, it is also flowingin the heat exchanger. And since it is a flowing fluid, it will have a convection coefficient.)
