A Fluid Velocity Tutorial

Here is another video describing the concepts of fluid velocity, pressure, and flow. It's from the Hydraulics collection offered by Columbia Gorge Community College.  In this video,  Instructor Jim Pytel, drives home fluid velocity concepts in a very entertaining and easy to understand way.  The video uses a humorous "application", where Mr. Pytel equates pressure to the system "strength", and flow as the system "speed". The video then goes on to explain the roles of pressure relief valves and flow control valves and how they allow for changes in force and speed of the sample system. It also introduces parallel and series hydraulic circuits, laminar and turbulent flow, flow rate, and flowmeters.
