Fluid Mechanics Lesson Series - Lesson 06D: Angular Momentum, Fixed CV In this 8-minute video, Professor Cimbala derives the angular momentum equation for a fixed control volume by utilizing the Reynolds Transport Theorem. He then shows some simplifications and works out an example problem. He takes special care to explain the signs associated with the various moments acting on the control volume. This video incorporates material from Sections 6-5 and 6-6 of the Fluid Mechanics textbook by Cengel and Cimbala. An Excel file listing of all the videos in this series can be found at .
