WebDarcy-Weisbach Friction Loss Equation: D is called the "duct diameter" to keep the terminology general to include circular pipes and non-circular pipes, also known as ducts. For rectangular pipes (ducts), D=4A/P is known as the hydraulic diameter. WebThe Modified Hazen-Williams formula is derived from the Darcy-Weisbach and Colebrook-White equations and is given as: V = 3.83C R d 0.6575 (g.s) 0.5525 / v 0.105. Where, C R = dimensionless coefficient of roughness d = pipe diameter (m) g = acceleration due to gravity (9.81 m/s 2) s = friction slope (H L / L) v = viscosity of the fluid
