Applied Thermodynamics-II deals with the detailed study of Air Compressors such as Reciprocating, Rotary and Dynamic Air Compressors, including their Constructional and Thermodynamic Study. The subject then deals with one specific application of Air Compressors, i.e. Gas Turbines. It explains the Thermodynamic Aspects of Gas Turbines and their Derivatives. Also, the subject provides a brief description of different Jet Propulsion methods.
