A heat exchanger will be used to cool 150 kg/h fruit juice containing 12% dry matter from 80 °C to 30 °C. The inlet temperature of the cooling water is 15 °C. Calculate the amount of cooling water required for the outlet temperature of the cooling water to be 25 °C. If the water flow rate is increased by 20% during the process, what will the cooling water outlet temperature be?
