Question

During an experiment, a plate heat exchanger that is used to transfer heat from a hot water stream to a cold water stream is tested. The data in the table below are obtained. The heat transfer area is calculated to be 0.0400 m

(a) Calculate the rate of heat transfer to the cold water

(b) Calculate the overall heat transfer coefficient

(c) Determine if the heat exchanger is truly adiabatic. If not,

determine the fraction of heat loss and calculate the heat

transfer efficiency

(d) Determine the effectiveness and the NTU values

Also discussed if the measeured values are reasonable

state any assumption
