λ =  Pipe Friction Coefficient
Calculation of the pipe friction coefficient λ (friction coefficient in Darcy’s formula)
(For laminar flow: Reynolds number ≤ 2300) λ = 64/Re
(For turbulent flow: Reynolds number ≥ 2300) 1/λ^0.5 = -2 * Log10(ε/d/3.71 + 2.51/Re/λ^0.5) Calculated using the Colebrook-White equation
(Moody curve).
