Entropy
Learning Objectives
I.Apply the second law to processes. |
| | | II.Define a new property called entropy as it applies to commonly encountered engineering processes. |
| | | III.Discuss the Clausius inequality, which forms the basis for the definition of entropy. |
| | | IV.Explain the increase of entropy principle. |
| | | V.Calculate the entropy changes that take place during processes for pure substances, incompressible substances, and ideal gases. |
| | | VI.Examine a special class of idealized processes, called isentropic processes and develop the property relations for these processes. |
| | | VII.Derive the reversible steady-flow work relations. |
| | | VIII.Develop the isentropic, or adiabatic, efficiencies of various steady-flow engineering devices and apply the definitions to turbines, compressors, and nozzles. |
| | | IX.Introduce and apply the entropy balance to various systems. |
