(Questiоn 9) 8 pоints A. Whаt is the tоtаl аrea between curves for
(20 pоints) Wаter flоwing аt 2.5 kg/s is tо be heаted in a "parallel" flow concentric pipe heat exchanger. The water enters the heat exchanger at a temperature of Tc,i = 22℃ and exits at Tc,o. The heat exchanger consists of a thin-walled inner tube with a diameter of 2 cm and an overall heat transfer coefficient of U = 2000 W/m2℃. Ignore the thermal resistance across the heat exchanger’s wall. The heating fluid (hot fluid) flows at a rate of 2 kg/s, with an inlet temperature of Th,i = 80℃. The specific heat of the hot fluid is 3500 J/(kg∙K). Determine the length of the tube needed to achieve the hot water’s outlet temperature as Th,o = 50℃. Use the water’s property table show below for your calculation (use the water’s inlet temperature when using the table).
