In principle, the maximum possible heat exchange would be achieved with a counterflow heat exhanger of infinite length. In such a heat exchanger the maximum possible temperature difference achieved (by one of the fluids) would be equal to T hi −T ci. For example, the cold fluid would be heated to the inlet temperature of the hot fluid, or the ...
Explain some phenomena that involve conductive, convective, and radiative heat transfer; Solve problems on the relationships between heat transfer, time, and rate of heat transfer; Solve problems using the formulas for conduction and radiation
(G) analyze and explain everyday examples that illustrate the laws of thermodynamics, including the law of conservation of energy and the law of entropy.
16 Αυγ 2021 · Law of Heat Exchange: When a hot body is mixed or kept in contact with a cold body, the hot body loses heat and its temperature falls. On the other hand, the cold body absorbs the heat lost by the hot body and the temperature of the cold body increases.
Explain heat, heat capacity, and specific heat; Distinguish between conduction, convection, and radiation; Solve problems involving specific heat and heat transfer
18 Σεπ 2022 · Conduction requires contact. Convection requires fluid flow. Radiation does not require any medium. Conduction is heat transfer directly between neighboring atoms or molecules. Usually, it is heat transfer through a solid. For example, the metal handle of a pan on a stove becomes hot due to convection.
An important idea in solving calorimetry problems is that during a heat transfer between objects isolated from their surroundings, the heat gained by the colder object must equal the heat lost by the hotter object, due to conservation of energy:
