A heat exchanger operates steadily as shown in Figure Q2. Air enters the heatexchanger at 100 kPa, 25°C and leaves at 95 kPa, 50°C. Refrigerant-134a (R-134a)enters the heat exchanger at 700 kPa, 50°C with a mass flow rate of 0.15 kg/s andleaves as saturated liquid at 700 kPa. The heat exchanger is well insulated and heattransfer occurs only between the R-134a and air. Changes in kinetic energy andpotential energycan be neglected. Assume air asideal gas andantake c,=1.005 kJ/kg.K.i)Determine the rate of heat transfer between the R-134a and air, kW.ii) Calculate the mass flow rate of air, kg/s.iii) Determine the inlet velocity of R-134a if the diameter of the pipe is 5 cm, m/s.
