2013-3-6 Learning Outcomes,cont. Assess the performance of power cycles and refrigeration and heat pump cycles using,as appropriate,the corollaries of Secs.5.6.2 and 5.7.2,together with Egs 5.9-5.11. Describe the Carnot cycle. Interpret the Clausius inequality as expressed by Eq.5.13. Aspects of the Second Law of Thermodynamics From conservation of mass and energy principles,mass and energy cannot be created or destroyed. For a process,conservation of mass and energy principles indicate the disposition of mass and energy but do not infer whether the process can actually occur. The second law of thermodynamics provides the guiding principle for whether a process can occur. 2 2013-3-6 2 Learning Outcomes, cont. ►Assess the performance of power cycles and refrigeration and heat pump cycles using, as appropriate, the corollaries of Secs. 5.6.2 and 5.7.2, together with Eqs. 5.9-5.11. ►Describe the Carnot cycle. ►Interpret the Clausius inequality as expressed by Eq. 5.13.
