Learning Activity 7.3: Data for the Pump-down Curve with Wet Paper Tissue

This video, published by Erie Community College, features an experiment that involves a Rough Vacuum System Trainer (RVET) undergoing the pump-down process with a wet paper tissue simulating a wet contaminant. The experiment lasts five minutes and includes a pressure gauge with the current atmospheric pressure, allowing learners to record changes in pressure throughout the pump-down process. The data collected from this experiment can be used to create a pump-down curve in learning activity seven of the lab manual.

The video corresponds with lessons in a student lab manual and instructor guide that accompanies the Introduction to Vacuum Technology E-book. This textbook provides an introduction to vacuum technology and science, and features topics curated to the needs of technicians in a production environment. The guides include student questions and a data table corresponding to the video.

The video runs 6:59 minutes in length. The E-book, and related student and instructor guides, videos, and labs are available to view separately.
