Steam in the condenser of a steam power plant is to be condensed at a temperature 500C (hfg = 2383 kJ/ kg) with cooling water (Cp = 4180 J/kg) from a nearby lake, which enters the condenser at 180C and leaves at 270C. The surface area of the tubes is 42 m2 and the overall heat transfer coefficient is 2400 W/ m2 .0C. Determine: (i) The mass flow rate of cooling water needed (ii) The rate of condensation of steam in the condense
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.
