This lesson covers the application of thermodynamics in real-world scenarios, focusing on the operation of diffusers, compressors, and nozzles. It explains how to calculate the ratio of exit flow area to the inlet flow area, the exit velocity, and the rate of entropy generation. The lesson also discusses the concept of isentropic efficiency and how to calculate it. It provides a step-by-step guide on how to solve problems related to these topics, using specific gas constants, temperatures, pressures, and velocities. For instance, it demonstrates how to calculate the exit velocity of a diffuser that decelerates the flow from 200 m/s to 126 m/s.
