In any process industry, we need to transfer heat for different operations (like cooling, heating, vaporizing, or condensing) to or from various fluid streams in various equipment like condensers, waterheaters,reboilers,airheatingorcoolingdevicesetc.,whereheatexchangesbetweenthetwo fluids.Inachemicalprocessindustry,theheatexchangerisfrequentlyusedforsuchapplications.A heatexchangerisadevicewheretwofluidsstreamscomeintothermalcontactinordertotransfer theheatfromhotfluidtocoldfluidstream. In thischapter,we will discussabout thetechnical analysis of the heat exchangersalong with the method for predicting heat exchanger performance and operational parameters. Moreover the discussiononheatexchangersizewillalsobediscussed.However,wewillnotdiscusstheeconomics (though discuss the heat exchanger size) of the heat exchanger. We will consider that the heat transferwillprimarily betakenby conduction and convection only.Wewilldescribethecommonly usedheatexchangersandtheirimportantcharacteristics. Ingeneralheatexchangers may becategorized into two general classes depending on therelative i t ti f th fl di ti f th t fl id t If th t t th i
