In a heat exchanger, inlet and outlet temperatures of cooling water are 28ᵒC and 33ᵒC. The cooling water circulation is 200 litres/hr. The process fluid enters the heat exchangers at 60ᵒC and leaves at 45ᵒC. Find out the flow rate of the process fluid (cp of process fluid = 0.95). Sketch the energy balance using block/flow diagram and label the components.
