A double-pipe parallel-flow heat exchanger is to heat water (cy = 4180 JAGK) from 25°C to 60°C at a rate of 0.2 k g's. The he ating is to be accomplished by geothermal water (cp = 4310 J/kg K) available at 1 50°C at a mass flow rate of 0.25 kg/s. The inner tube is a thin walled and has a diameter of 0.8 cm. If the overall he at transfer coefficient of the heat ex changer is 550 W/m2 K, determine the length of the tube required to achieve the desir ed he ating

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.
Question
Transcribed Image Text:A double-pipe parallel-flow heat exchanger is to heat water (Cp= 4180 JAgK) from
25°C to 60°C at a rate of 0.2 k g/s. The heating is to be accomplished by geotherm al
water (Cy = 4310 J/kg K) available at 150°C at a mass flow rate of 0.25 kg/s. The inner
tube is a thin- walled and has a diameter of 0.8 cm. If the overall heat transfer coefficient
of the heat ex changer is 550 Wm2 K, determine the length of the tube required to
achieve the desired heating
