Hot water at 60℃ is cooled to 36℃ through the tube side of a 1–shell pass and 2-tube passes heat exchanger. The coolant is also a water stream, for which the inlet and outlet temperatures are 7℃ and 31℃, respectively. The overall heat transfer coefficient and the heat transfer area are 950 W/m2 K and 15 m2 , respectively. Calculate the mass flow rates of hot and cold water streams in steady operation. (Answers: 3.63 kg/s for both stream)
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.
