Steam is to be condensed on the shell side of a 1-shellpass and 8-tube-passes condenser, with 50 tubes in each pass, at 308C (hfg 5 2431 kJ/kg). Cooling water (cp 5 4180 J/kg?K) enters the tubes at 158C at a rate of 1800 kg/h. The tubes are thin-walled, and have a diameter of 1.5 cm and length of 2 m per pass. If the overall heat transfer coefficient is 3000 W/m2 ?K, determine (a) the rate of heat transfer and (b) the rate of condensation of steam.
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.
