The experiment was performed with a set of pipes of which. D h, fitting the data of experimental studies of turbulent flow in smooth and rough pipes. A robust, fast, and accurate method for solving the colebrook like equations is presented. The algorithm is also faster and more robust than the colebrook solution expressed in term of the. Figure 1 from solution of the implicit colebrook equation. Colebrook in 1939 and it is based on his joint experiment, which was performed with prof. The paper presents a problem that requires iterative methods for the solution. In the post below, i demonstrate how to create a colebrook equation solver in excel. The algorithm is efficient for the whole range of parameters involved in the colebrook equation.

Within chemical engineering, there are a lot of problems involving fluids in motion, and for their solution we must consider the causes of the movement. The phenomenological colebrook white equation or colebrook equation expresses the darcy friction factor f as a function of reynolds number re and pipe relative roughness. The computations are not more demanding than simplified approximations, but they are much more accurate. What can students learn while solving colebrooks flow. The colebrook equation for flow friction is an empirical formula developed by c. Figure 1 from solution of the implicit colebrook equation for. A robust, fast, and accurate method for solving the colebrooklike equations is presented. The colebrook or colebrook white equation is the best way to dynamically determine the darcyweisbach friction factor for turbulent pipe flow. The experiment was performed with a set of pipes of which the inner side was covered with sand of. The equations were developed via a curve fit to many experimental data points. Efficient resolution of the colebrook equation industrial. In particular, the implicit method used for calculating the continue reading.
