A shell-and-tube heat exchanger uses cooling water in the tubes. There are two pressure gages installed on the the water side to the heat exchanger. Gage 1 (P1) is installed on the inlet water line, which is connected to the lower nozzle, while Gage (P2) is installed on the discharge water line, which is connected to the upper nozzle. Both pressure gages are very near the nozzle flanges. The pressure drop from each pressure gage to the exchanger channel is...

An insulated heat exchanger uses geothermal water to heat water for a chemical plant. Water enters the heat exchanger at a rate of 36 kg/s and is heated from 23 ∘∘C to 69 ∘∘C. The geothermal water enters the exchanger at a rate of 41.4 kg/s and at an initial temperature of 130 ∘∘C. The specific heat of the geothermal water is 4.31 kJ/(kg K). Determine the rate of heat transfer between the two streams and the rate of entropy...

A counter-flow double-pipe heat exchanger is to heat water from 20ºC to 80ºC at a rate of 1.2 kg/s. The heating is to be accomplished by geothermal water available at 160ºC at a mass flow rate of 2 kg/s. The inner tube is thin-walled, and has a diameter of 1.5 cm. If the overall heat transfer coefficient of the heat exchanger is 640 W/(m2.ºC), determine the length of the heat exchanger required to achieve the desired heating using the effectiveness-NTU...

Saturdated water vapor (steam) is commonly used as a heat source in heat exchanger applications. Why saturated vapor? Why saturated water vapor? In a plant of any reasonable size, several varieties of saturated steam are commonly available; for example, saturated steam at 4.5,9,17, and 33 bar. But the higher the pressure the lower the useful energy content (why?), and the greater the unit cost. Why then is higher-pressure steam used?
