Fluid Mechanics Lesson 14B: Aerodynamic Drag on Various Objects

Fluid Mechanics Lesson Series - Lesson 14B: Aerodynamic Drag on Various Objects. In this 8-minute video, Professor Cimbala shows tables of drag coefficients for both two-dimensional and three-dimensional objects (geometric shapes, parachutes, bicycles, trees, etc.). In the process he explains how streamlining can greatly reduce the drag coefficient. He does a detailed example of how to estimate the drag area of a bicycle/rider combination by coasting down a hill. He then shows how the calculated drag area can be used to predict the power which the rider must apply to the pedals in order to travel at constant speed on a level road. This video incorporates material from Sections 11-3 and 11-4 of the Fluid Mechanics textbook by Cengel and Cimbala, Edition 4. An Excel file listing of all the videos in this series, along with the annotated notes generated during filming of the videos, can be found at https://www.me.psu.edu/cimbala/Cengel... .
