A chemical having specific heat of 3.3 kJ/kg K flowing at the rate of 20,000 kg/h enters a parallel flow heat exchanger at 120°C. The flow rate of cooling water is 50000 kg/h with an inlet temperature of 20°C. The heat transfer area is 10m2 and the overall heat transfer coefficient is 1050 W/m2K. Find the outlet temperatures of water and chemical and effectiveness of the heat exchanger. Take for water specific heat = 4.186 kJ/kg K.
