The condenser of a large thermal power plant consists of a single body with two passes each and 30000 pipes. It is a shell and tube type heat exchanger. Pipes are 25 mm inner diameter, thin-walled and steam, 11000 W / m2 With a convection coefficient of .K, it condenses on the outer surfaces of the pipe. Heat The transfer required by the exchanger is 2000 MW, and 30000 kg / h of water will be transferred from the pipes. as with flowing flow rate. Water enters at a temperature of 20 ° C, steam at 50 ° C. is condensing. Calculation temperature of the cooling water from the condenser? Required per pass determine the pipe 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.
