Fluid Mechanics Lesson Series Lesson 15A: OneDimensional Compressible Flow in Ducts.

In this 15minute video, Professor Cimbala starts with a quick review of compressible flow concepts, such as Mach number regimes. He then discusses the importance of thermodynamics for compressible flows, in particular the isentropic and adiabatic approximations. He then defines and discusses stagnation properties. Finally, he analyzes the conservation of mass equation for onedimensional duct flow, comparing and contrasting the supersonic vs. subsonic flow behavior. He works through two example problems as well.

This video incorporates material from Sections 121 and 122 of the Fluid Mechanics textbook by Cengel and Cimbala, Edition 4.
