A double-pipe parallel-flow heat exchanger is used to heat water (cp = 4180 J/kg·K) from 25°C to 60°C at a rate of 0.2 kg/s. The heating is accomplished by geothermal water (cp = 4310 J/kg·K) available at 134°C at a mass flow rate of 0.3 kg/s. The inner tube is thin-walled and has a diameter of 0.8 cm. If the overall heat transfer coefficient of the heat exchanger is 550 W/m2·K, determine the length of the tube required to achieve the desired heating. (Round the answer to a single decimal place.) The length of the tube required to achieve the desired heating is ____
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.
