7.21- In a textile manufacturing plant, the waste dyeing water (Cp = 4295 J/g Cº) at 75C° is to be used to preheat fresh water (Cp = 4180 J/kg ·Cº) at 15C° at the same flow rate in a double-pipe counter-flow heat exchanger. The heat transfer surface area of the heat exchanger is 1.65m² and the overall heat transfer coefficient is 625 W/m² Cº. If the rate of heat transfer in the heat exchanger is 35kW, determine the outlet temperature and the mass flow rate of each fluid stream.
