1. A) Describe Moody’s chart and its importance in your own words. Also explain how do you find the friction factor by using the chart?

B) If the friction factor is 0.04 and the relative roughness is 0.004 then find the type of flow? (1 mark)

Solutions

Expert Solution

The Moody chart or Moody diagram is a graph in non-dimensional form that relates the Darcy-Weisbach friction factor fD, 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 or Moody chart is the plot of the relative roughness (e/D) of a pipe against the Reynold's number. ... It was this chart which first enabled the user to obtain a reasonably accurate friction factor for turbulent flow conditions, based on the Reynolds number and the Relative Roughness of the pipe
