Moody Chart Calculator: How Does It Work? The underlying equation that was used to create the Moody chart can be solved to obtain a numerical result for the Darcy friction factor . Each of the curves on a Moody diagram represent the result of an equation that describes the Darcy friction factor as a function of the relative roughness and Reynolds number. The equations used in this program represent the Moody diagram which is the old-fashioned way of finding f. You may enter numbers in any units, so long as you are consistent. (L) means that the variable has units of length (e.g. meters). (L 3 /T) means that the variable has units of cubic length per time (e.g. m 3 /s).

Moody diagram calculator. In engineering, the Moody chart or Moody diagram (also Stanton diagram) is a graph in non-dimensional form that relates the Darcy-Weisbach friction factor f D, Reynolds number Re, and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe. The friction factor f can be determined using the Moody diagram shown in Figure 4.2 as follows: 1. For the given flow rate, liquid properties, and pipe size, calculate the Reynolds number of flow using Equation (4.8). 2. Calculate the relative roughness (e/D) of the pipe by dividing the pipe absolute roughness by the inside diameter of the pipe. From Reynolds number and roughness. Serghide's solution to the Colebrook-White equation is used to approximate the Darcy friction factor within full flowing pipes with a Reynolds number (Re) above 4000. It tends to be very accurate to the iteratively determined Colebrook-White equation - within ~30 ppm accuracy. Download the freeMoody Chart Calculator app from Google Play here.

Nov 23, 2021 · One of the commonly used approximation is given by Lewis Moody, otherwise known as Moody chart or Moody diagram. This calculator utilizes Moody's approximation to determine the Darcy friction factor. Moody's approximation or otherwise known as Moody equation is given as: f = 0.0055 ( 1 + (2 * 10 4 * k/D + 10 6 /Re) 1/3) friction factor, f, rather than a graph like the Moody diagram.
