Question

A well-insulated, thin-walled, counter-flow heat exchanger is to be used to cool oil (cp = 2.20 kJ/kg∙ oC) from 150 to 40oC at a rate of 2 kg/s by water (cp = 4.18 kJ/kg∙oC) that enters at 22oC and leaves at 40oC. Assuming a steady flow system, determine (a) the required mass flow rate (kg/s) of cooling water necessary to meat the desired cooling rate (b) heat transfer rate (kW).
