In a parallel flow heat exchanger, with a cooler at 40 °C at a flow of 2 kg / h, hot water at 1 kg / h is cooled from 90 ° C to 60 ° C.

The total heat transfer coefficient is 1000 W / m2K. Cph = Cpc = 4182 J / kgK. According to this;

d) Assuming that the exit temperature of the hot fluid is not given, for the case of the parallel flow heat exchanger, take the area of 6.42 m2 and calculate the exit temperature of the hot water using the efficiency-NTU method.
