Answer to Question #280393 in Chemical Engineering for Durga

Question

A hot fluid at 200 °c enters a heat exchanger at a mass flow rate of 10000kg/hr. It's specific heat is 2000j/kg°c. It is to be cooled by another fluid enters at 25°c with a mass flow rate 2500kg/hr and specific heat is 400 j/kg°c. The overall heat transfer coefficient based on outside area of 25m^2 is 250W/m^2°c. Find the exit temperature of the hot fluid when the fluid are in parallel flow and counter flow
