When discussing air pressure related to ventilation systems, the basic terms “total”, “dynamic”, “velocity”, “static”, “drop”, and “loss” are often used. How these pressure terms are applied and the means for measuring them can be confusing. In part one of this two part series, I will provide some clarity to understanding pressure terminology. Static Pressure …
