Thermodynamic Processes and Equations

Thermodynamic Processes and Equations! A process is a change in the state of a gas as a result of flow of energy. During this flow a change takes place in properties of the substance such as pressure, volume, temperature and also the energy quantities such as internal energy, heat and work. The five important processes commonly dealt with in engineering [...]

Classification of Thermodynamic Cycles

Classification of Thermodynamic Cycles! Thermodynamic Cycle # I. Carnot Cycle: It consists of two isothermal processes and two isentropic processes. This cycle is represented on temperature-entropy and pressure-volume diagrams as shown in fig. 2-34. Consider one kg of air at temperature T1 as the working fluid in the engine cylinder. Let point 1 (fig. 2-34) represent the state of the [...]
