WebFeb 20, 2024 · Flow is proportional to pressure difference and inversely proportional to resistance: Q = P2 − P1 R. For laminar flow in a tube, Poiseuille’s law for resistance states that R = 8ηl πr4. Poiseuille’s law for flow in a tube is Q = (P2 − P1)πr4 8ηl. The pressure drop caused by flow and resistance is given by P2 − P1 = RQ. WebAir Flow Equations for working out the velocity of air coming through a hose or tube and the pressure loss of the air going through these. Velocity of Air in Feet per Second = √ (25,000 * Loss of Pressure in Ounces per Square Inch * Inside Diameter of the Pipe in Inches) / Length of Pipe in Feet. Loss of Pressure in Ounces per Square Inch ...
