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.
Some examples of common design parameters to be taken into account are: • Flow rate of both fluid streams • Inlet and outlet temperatures of both streams • Operating pressure of both streams • Allowable pressure drop of both streams • Fouling resistance for both streams • Physical properties of both streams • Type and ...
The general function of a heat exchanger is to transfer heat from one fluid to another. The basic component of a heat exchanger can be viewed as a tube with one fluid running through it and another fluid flowing by on the outside.
What heats faster, land or water? You will answer this question by taking measurements to study differences in specific heat capacity.
In these examples, heat is transferred by radiation (Figure \(\PageIndex{10}\)). That is, the hot body emits electromagnetic waves that are absorbed by the skin. No medium is required for electromagnetic waves to propagate.
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 transfer restores thermal equilibrium once the water and pan are in contact; it stops once thermal equilibrium between the pan and the water is achieved. The heat lost by the pan is equal to the heat gained by the water—that is the basic principle of calorimetry. Solution
