Water at a temperature of 93.3 C is pumped from a tank with a flow rate of 0.189 m3/min at latm absolute pressure. The motor that moves the pump gives 1.49 kW of energy. As the water passes through a heat exchanger at the pump outlet, it loses 704 kW of heat and then enters another tank open to the atmosphere at a height of 15.24 m from the first tank. Find the temperature of the water in the second tank according to these data. Calculate what the gain in enthalpy of the water is due to the workgiven to the pump.
