Fanning's equation
WebIt is determined by the Colebrook equation or can be determined using the Moody chart. The Moody chart for Re = 575 600 and ε/D = 5 x 10-4 returns following values: the Darcy friction factor is equal to f D = 0.017; the Fanning friction factor is equal to f F = f D /4 = 0.00425. Therefore the skin friction coefficient is equal to: WebFeb 24, 2024 · Eq. (1) is Fanning's equation. ・・・. where Δ P is the pressure drop, f is the friction coefficient, ρ is the liquid density, u is the liquid velocity, L is the pipe length, d is the pipe diameter. When calculating the pump head in head [m], use Eq. (2), where both sides of Eq. (1) are divided by ρg.
