[ \Delta P = \rho \cdot g \cdot \Delta h ] What Is Pressure Difference

1. Executive Summary Pressure difference is the fundamental driving force for the movement of fluids (liquids, gases, and vapors) in nature and engineered systems. It is defined as the difference in pressure between two points in a fluid or across a barrier. Without a pressure difference, there is no net flow, no buoyancy, no ventilation, and no pneumatic or hydraulic actuation. This report explores the physics, measurement, applications, and safety implications of differential pressure. 2. Fundamental Definition Pressure ((P)) is defined as force per unit area: ( P = \fracFA ) (Pascals, Pa, or N/m²). [ \Delta P = f \cdot \fracLD \cdot
