• Water is stored in a large, insulated storage tank at a temperature of 21.0 °C and atmospheric pressure. Water is pumped at steady state from the tank It uses a pump with a flow rate of 40 m3 /h. the motor that driving the pump supplies 8.5 kW of energy. Water is used as cooling medium and passes through a heat exchanger where there is a heat of 255 kW added to the water. The hot water then flows into the second tank which is located 25 m above the first tank. Determine the final temperature of the water delivered to second tank.
