For each different modes, these variables will be changed to match the mode. To solve for x, estimate a value for d, then solve for x, then use the x for the next value of d. Solve for x again and again until x does not change (usually 7 loops for 14 or 15 decimals of accuracy.). Then the

- The Colebrook-White equation is the currently accepted world standard for pipeline design. 1 / λ 1/2 = -2 Log [ 2.51 / (Re λ 1/2 ) + (k / d h ) / 3.7 ] where λ is the friction coefficient Today the Colebrook-White equation is the currently accepted world standard form of the Darcy-Weisbach equation.
- which is also known as the Colebrook equation, expresses the Darcy friction factor f as a function of pipe relative roughness ε / D h and Reynolds number. In 1939, Colebrook found an implicit correlation for the friction factor in round pipes by fitting the data of experimental studies of turbulent flow in smooth and rough pipes.
