The following video tutorials may be viewed using the Adobe Flash Player Measuring Pumping Speed. Effective pumping performance is determined experimentally using the relationship between Q (throughput or mass flow), Pressure and Pumping Speed. Closed-Loop Pressure Control in Vacuum Systems. This is a brief overview of closed-loop pressure control as applied to vacuum process systems. Included are a number of video captures that show actual system response to changes in set point using a variety of tuning parameters. Gas Flow Through an Orifice. This tutorial discusses orifices in the choked and unchoked conditions. Included are several video captures that show orifice flow characteristics in a couple of different test configurations.
