Friction factor calculator

WebNote! - be aware that there are two alternative friction coefficients present in the literature. One is 1/4 of the other and (1) must be multiplied with four to achieve the correct result. This is important to verify when selecting friction coefficients from Moody diagrams. The Colebrook friction coefficient calculator corresponds to equation (1). WebThe Darcy Weisbach equation is shown below: where: Δp = pressure loss [Pa] L = the length of the pipe [m] fD = Darcy friction factor (or Darcy Weisbach friction factor) …
