原始语种摘要： | The paper presents relation for maximal pressure-volume work for closed systems by using principles of I and II law of thermodynamics, used in reversible processes in which mechanical and thermal balance has been achieved. For full interpretation of this problem for two characteristic cases, graphical review in p-v diagram is given, where in an obvious way is noticed that maximal expansion work is composed of isentropic and isothermal work as well as work against pressure of environment. On basis of derived relation, by using appropriate thermodynamic relations, expression for specific maximal work is obtained which is suitable for the analysis. That expression was observed like two-dimensional problem i.e. as function of two variables: initial pressure and initial temperature as primary... |
