Jul 13, 2009 · If you try to just add sqrt (A3), you get a division by zero error because the initial value of the cell is zero. One way to get around this is to add a tiny little number to A3 like this: "=1/ (-2*LOG (A2/3.7 + 2.51/ (A1*SQRT (A3+1E-300))))^2". This equation now agrees with Colebrook-White to many decimal places.
To implement this procedure in Excel in order to solve the implicit Colebrook-White equation the ‘Office button’ at the upper left corner of the screen need to be pressed (Figure 3) where in ‘Excel options’, ‘Formulas’ needs to be selected (this procedure can be slightly different in …
Jan 17, 2010 · The returned result is of course the Darcy friction factor, which is meant to be used with the Darcy-Weisbach equation to calculate pressure drop. Function Colebrook(R As Double, K As Double) As Double Dim X1 As Double, X2 As Double, F As Double, E As Double X1 = K * R * 0. X2 = Log(R) - 0. F = X2 - 0.

Colebrook Equation Solver in Excel. The Colebrook (or Colebrook-White) equation is the best way to dynamically determine the Darcy-Weisbach friction factor for turbulent pipe flow. The equations were developed via a curve fit to many experimental data points.
Solving Colebrook Equation for Pipe Design, Sizing and Optimisation Calculations: Solve Within Excel Worksheet - No VBA, MACRO, UDF of SOLVER [Kumar, ...
Solving the Colebrook-White Equation with Excel. The Colebrook-White describes the relationship between the Reynolds Number Re, the pipe relative roughness e, and the friction factor f in turbulent pipe flow. Usually, we fix a value for Re and e, and compute f. However, this equation cannot be solved explicitly, so numerical iteration is needed. There's several ways we can do this in Excel.
