Fluid Mechanics Lesson 01E: Vapor Pressure and Viscosity

Fluid Mechanics Lesson Series - Lesson 01E: Vapor Pressure and Viscosity In this 12-minute video, Professor Cimbala discusses two fluid properties: Vapor pressure and viscosity. When local fluid pressure dips below the fluid's vapor pressure, a phenomenon called cavitation is likely to occur. This is where the fluid "boils" locally, causing cavitation bubbles. Several consequences of cavitation are given. Viscosity is a measure of friction between moving portions of fluid. Several examples are given about how to calculate the friction exerted on a solid wall due to viscosity in a flowing fluid. This video incorporates material from Sections 2-3 and 2-6 of the Fluid Mechanics textbook by Cengel and Cimbala.
