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

3. In a shell-and-tube heat exchanger, water enters at 85°C at the rate of 5.4 kg/s. Engine oil enters at 20°C and leaves at 60°C. The water leaves the heat exchanger at 57°C. What is the mass flow rate of the engine oil? Express your answer in kg/s.

In a countercurrent double-pipe heat exchanger, the hot oil entering the inner tube at 420 K with a flow rate of 60 g/s is required to be cooled to 320 K. In the space between the outer tube and the inner tube of the heat exchanger, cooling water flows at the same linear speed as the oil. Cooling water enters the heat exchanger at 290 K. The inner tube inner diameter of the heat exchanger is 25 mm and the outer tube inner diameter is 40 mm. Calculate the length of the heat exchanger. The oil side heat transfer coefficient is 1.6 kW/m2 K, and the water side heat transfer coefficient is 3.6 kW/m2 K. The densities of oil and water can be taken as 0.8 and 1.0 g/cm3, respectively, and the specific heats of oil and water can be taken as 2.0 and 4.2 kJ/kg K, respectively. Wall effects can be neglected. Flow cross-sectional area = (PI)*D2 /4 F2
