Unformatted text preview: ME 200: Thermodynamics I Lecture 20: System Integration Prof. Sojka Summer 2011 October 13 th , 2010M E 2002 In this Lecture We will: Analyze integrated systems . 3 Example 1 A gas turbine operating at steady state with air as the working fluid is shown. Components include an air compressor mounted on the same shaft as the turbine, a high-pressure heat exchanger for heating air before it enters the turbine, and a low-pressure heat exchanger where air is cooled before returning to the compressor. Kinetic and potential energy effects are negligible. The compressor and turbine are adiabatic. Air is an ideal gas, find: power required for the compressor, in hp, power output of turbine, in hp, and thermal efficiency of the cycle.
