Pham, Q.T. 1979 Explicit equations for the solution of turbulent pipe-flowproblems. Trans. Inst. Chem. Eng. 57:281-283.

AbstractExplicit equations are obtained by re-arranging Colebrook's equation to solve the followingcommon pipe flow problems in the turbulent flow region: (a) Calculation of pressure drops,(b) Calculation of pipe diameters, (c) Calculation of flow rates.
