A condenser of a thermal power plant operates as a surface heat exchanger, 10,000 kg / h of water vapor enters at 0.5 bar and with a quality of 0.95 and the condensate leaves as a saturated liquid at the same pressure. The cooling water enters the condenser as a separate stream at 1 bar and 20 ° C and exits at 35 ° C without pressure change, assuming steady state operation, determine: a) The temperature of the condensed steam b) The amount of cooling water required in m3 / s c) The heat energy transmitted by the steam to the cooling water in Kw

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.
