The Moody chart or Moody diagram is a graph in non-dimensional form that relates the Darcy-Weisbach friction factor f D, Reynolds number Re, and relative roughness for fully developed flow in a circular pipe.It can be used for working out pressure drop or flow rate down such a pipe.

Reynolds Number. where, Re is the Reynolds Number. ρ is the density of the fluid. v is the velocity of the fluid. D is the diameter of the pipe. μ is the viscosity of the fluid. Moody Diagram The Moody diagram (also known as the Moody chart) is a graph in non-dimensional form that relates the Darcy friction factor, Reynolds number, and the relative roughness for fully developed flow in a circular pipe. Source: Donebythesecondlaw at the English language Wikipedia, CC BY-SA 3.0, Example: Moody Diagram. Using the Moody diagram, determine the friction factor (f D) for fluid flow in a pipe of 700mm in diameter with a Reynolds number of 50 000 000 and an absolute roughness of 0.035 mm. Solution: The relative roughness is equal to ε = 0.035 / 700 = 5 x 10-5.Using the Moody Chart, a Reynolds number of 50 000 000 intersects the curve corresponding to a relative roughness of 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. 3.

It also depicts the number of peaks and valleys on a surface. The lower the number, the lower the irregularities, implying low surface roughness and a better surface finish. When professionals refer to surface finish, it is often 'surface 10 3 10 4 10 5 10 6 10 7 10 8 10 −2 10 −1 8 9 1.2 1.4 1.6 1.8 2 2.5 3 3.5 4 4.5 5 5.5 6 7 6 7 8 2 3 4 5 6 7 8 2 3 4 5 6 7 8 2 3 4 5 6 7 8 2 3 4 5 6 7 8 2 3 4 5 6 5 Other Mood Charts (PDF) There are also several ready-made mood charts available online. All you have to do is print them and start utilizing the tools. Here is a list of a few you can work with today: 1. Daily Mood Chart A simple chart that tracks your mood scale between 1-10 (10 being best, 1 being worst). Organized by textbook: learncheme.com/Explains how to read a Moody chart for determining frictional factors in pipe flow problems. Made by faculty at between laminar and turbulent flow. The gray region in the Moody chart reflects the fact that the friction factor can vary significantly in this region. 3. The fully rough zone (aka wholly turbulent zone, fully turbulent zone) in the Moody chart is a region where the friction factor is a weak function of the Reynolds number, but a strong The Moody diagram is a chart showing the Darcy friction factor of a pipe as a function of the Reynolds number for selected roughnesses of the pipe wall. 1
