Water at 90C is being pumped from a large storage tank at 1 atm abs at a rate of 0.189 m3/min by a pump. The motor that drives the pump supplies energy to the pump at a rate of 2 hp. The water pumped through a heat exchanger, where it gives up 700 kW of heat and is then delivered to a large open storage tank at an elevation of 20 m above the first tank. What is the final temperature of the water to the second tank? Neglect kinetic energy.
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
