Pressure drop in ducts
Pressure loss in ductwork has three components, frictional losses along duct walls and dynamic losses in fittings, and component losses in duct-mounted equipment. Due to physical items with known pressure drops, such as hoods, filters, louvers, or dampers.
How to Calculate Pressure Drop in Square Duct?
Pressure Drop in Square Duct calculator uses Pressure Drop = (0.6*Friction Factor in Duct*Length of Duct*Mean Velocity of Air^2)/((Side^2)/(2*(Side+Side))) to calculate the Pressure Drop, The Pressure drop in square duct formula is defined as the pressure drops in the direction of flow, the pressure drop is due to Fluid friction or Momentum change due to change of direction and/or velocity in square ducts. Pressure Drop is denoted by Pf symbol.
How to calculate Pressure Drop in Square Duct using this online calculator? To use this online calculator for Pressure Drop in Square Duct, enter Friction Factor in Duct (f), Length of Duct (L), Mean Velocity of Air (Vmean) & Side (S) and hit the calculate button. Here is how the Pressure Drop in Square Duct calculation can be explained with given input values -> 9.476693 = (0.6*0.8*19*15^2)/((9^2)/(2*(9+9))).
