Hot water flows thorough a parallel flow heat exchanger at a rate of 10 kg/min and is cooled by a cold water stream of flow rate 25 kg/min. The inlet temperatures of hot and cold water streams are 70 oC and 25 oC, respectively. The outlet temperature of the hot water is expected to be 50 oC. The individual convective heat transfer coefficient on both sides of the heat transfer area is 600 W/m2 .K. Take the specific heat for...

1. In a counterflow heat exchanger, the heat loss to the environment is to be included in the mathematical model. Considering the case of the hot fluid on the outside and the colder fluid on the inside, as shown in Figure below, sketch qualitatively the change that the inclusion of this consideration will have on the temperature distribution in the heat exchanger. Also, give the energy equation taking this loss into account. Hot Cold Energy loss 2. Experiments are carried...
