Vacuums in Pneumatic Systems (Part 1 of 2)

This video, published by Columbia Gorge Community College, is the first part of a two part lecture that examines vacuums in pneumatic systems, discussing "how vacuum conditions are measured, how vacuum is generated, and how vacuum is employed." This first part of the lecture primarily focuses on measuring vacuum, including a discussion of gauge pressure, absolute pressure, absolute height, and the vacuum scale. 

This video runs 9:03 minutes in length. The second part of the lecture is available to view separately.
