The heat exchanger is a very important device used in many real world applications in which heat must be transferred from one medium to another. In many cases, the two mediums are separated by a solid wall, although in some cases the two mediums are in direct contact with each other, so that mixing occurs.
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
For many decades, the tube-and-shell heat exchanger has been the workhorse of the chemical process industry, but the high heat transfer rates, and resulting compactness, of plate heat exchangers have made them the popular modern choice, especially for liquid-liquid systems.
Explain heat, heat capacity, and specific heat; Distinguish between conduction, convection, and radiation; Solve problems involving specific heat and heat transfer
Conceptual Questions. 15.1: The First Law of Thermodynamics. 1. Describe the photo of the tea kettle at the beginning of this section in terms of heat transfer, work done, and internal energy. How is heat being transferred? What is the work done and what is doing it? How does the kettle maintain its internal energy? 2.
Explain phenomena involving heat as a form of energy transfer; Solve problems involving heat transfer
Learning Objectives. By the end of this section, you will be able to: State the expressions of the second law of thermodynamics. Calculate the efficiency and carbon dioxide emission of a coal-fired electricity plant, using second law characteristics. Describe and define the Otto cycle. Figure 15.14 These ice floes melt during the Arctic summer.
