Turbines and Compressors: ConcepTest and Example Problem
Try to answer this ConcepTest and solve this example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. By the end of this module, you should be able to answer these on your own. Answers will be given later in this module.
Example Problem 1
Two turbines are used to expand an ideal gas from 1.0 MPa and 650 K to produce work. Turbine A has an efficiency of 70%, and turbine B has an efficiency of 50%. Under a certain set of operating conditions, the exit temperature of turbine A is measured to be the same as the exit temperature of turbine B. Under these conditions, which turbine is producing more work? Explain.
