100 kg/s of a crude oil is heated from 20°C to 40°C through the tube side of a multitube heat exchanger. The crude oil flow is divided evenly among all 100 tubes in the tube bundle. The ID of each tube is 10 mm, and the inside tubewall temperature is maintained at 100°C. Average properties of the crude oil are r = 950 kg/m3, cp = 1.9 kJ/kg?K, k = 0.25 W/m?K, m = 12 mPa?s, and mw = 4 mPa?s. Estimate the rate of heat transfer and the tube length.
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.
