Geankoplis 4th ed. 4.5‐4. Water flowing at a rate of 13.85 kg/s is to be heated from 54.5 to 87.8oC in a double‐pipe heat exchanger by 54,430 kg/h of hot gas flowing counterflow and entering at 427oC ( 1.005 / ).
Algebraic expressions for the correction factor Fhave been developed for vari- ous shell-and-tube and cross-flow heat exchanger configurations [1–3], and the results may be represented graphically. Selected results are shown in Figures 11S.1 through 11S.4 for common heat exchanger configurations.
Heat Exchangers DOE-HDBK-1018/1-93 TYPES OF HEAT EXCHANGERS. Plate. Figure 1 Tube and Shell Heat Exchanger. A plate type heat exchanger, as illustrated in Figure 2, consists of plates instead of tubes to separate the hot and cold fluids. The hot and cold fluids alternate between each of the plates. Baffles direct the flow of fluid between plates.

Heat • The temperature difference determines the direction of heat transfer. • Bodies don’t “contain” heat; heat always refers to energy in transit from one body to another. • We can change the temperature of a body by adding heat to it.
The natural laws of physics always allow the driving energy in a system to flow until equilibrium is reached. Heat leaves the warmer body or the hottest fluid, as long as there is a temperature difference, and will be transferred to the cold medium. A heat exchanger follows this principle in its endeavour to reach equalisation.
Thermodynamics is the branch of physics that deals with systems in which energy is in the form of heat, work, and internal energy. Such systems have a wide variety of practical applications, ranging from gasoline-fueled car engines to refrigerators and air conditioners.
