Calculation Tutorial
Air pressure loss, also called pressure drop, is the reduction in static pressure that happens when air moves through ductwork, fittings, filters, and other restrictions, and the reason engineers use a calculator to estimate it quickly. This walkthrough shows the Darcy-Weisbach formula, the K-factor model for fittings, and how to read the calculator output.
