To calculate friction factor (f) using the Colebrook formula, solve for fff by taking the logarithm of the sum of two terms: the pipe roughness divided by the diameter and the Reynolds number multiplied by the reciprocal of the friction factor. This equation is implicit and typically solved iteratively. The Colebrook formula calculator is actually…
