One of the fluids flows through the inside of the shell and the other fluid flows through tubes passing through the inside of the shell, thereby enabling heat transfer between the two fluids. Baffles are added to enhance the convection coefficient, which increases heat transfer between the two fluids.
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.
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.
1. What is heat transfer? a) Flow of thermal energy from low-temperature reservoir to high-temperature reservoir. b) Flow of energy in the form of heat from high-temperature reservoir to low-temperature reservoir. c) Flow of thermal energy irrespective of reservoir temperature. d) None of the above. View Answer. 2.
Rebecca tells Brent that the energy needed to change the phase of 1 kilogram of a substance is called the _________ heat. For example 333 kJ of energy is needed to melt 1 kilogram of ice. When ice is forming, _________ per kilogram must flow from the freezing water. Not all substances have the same latent heat.
In the boxes below, draw an example of each type of heat transfer. Explain how heat is being transferred in your example.
