4. Water at 85.0C is being stored in a large, insulated tank at atmospheric pressure as shown in Fig. 2.7-3. It is being pumped at steady state from this tank at point 1 by a pump at the rate of 0.567m3/min. The motor driving the pump supplies energy at the rate of 7.45kW. The water passes through a heat exchanger, where it gives up 1408kW of heat. The cooled water is then delivered to a second, large open tank at point 2, which is 20m above the first tank. Calculate the final temperature of the water delivered to the second tank. Neglect any kinetic-energy changes since the initial and final velocities in the tanks are essentially zero. 5. A nozzle of cross-sectional area A2 is discharging to the atmosphere and is located in the side of a large tank, in which the open surface of the liquid in the tank is Hm above the center line of the nozzle. Calculate the velocity v2 in the nozzle and the volumetric rate of discharge if no friction losses are assumed
