WebBecause of non-empirical origins, the Darcy-Weisbach equation is viewed by many engineers as the most accurate method for modeling friction losses. It most commonly … WebThe hydraulic diameter is used the Darcy-Weisbach equation to calculate pressure loss in ducts or pipes. Note! - the hydraulic diameter is not the same as the geometrical equivalent diameter of non-circular ducts or pipes. Hydraulic diameter can be calculated with the generic equation dh = 4 A / p (1) where dh = hydraulic diameter (m, ft)
