A 95kg/hr hot fluid is used to heat a cold fluid from 6oC to 63oC using a double pipe heat exchanger (DPHE). The hot fluid enters at 205°C and leaves the DPHE at 112°C. The Cp of hot fluid is 1.10 kcal/kg°C and the Cp of cold fluid 0.95 kcal/kg°C. Find the mass flow rate in kg/hr of cold fluid if the heat loss during the exchange is 10%.
