OR Draw rough nature of Moody Chart showing different regimes of fluid flow and explain its significance

The Moody chart or Moody diagram is a graph in non-dimensional plot that relates the Darcy Weisbach friction factor (f), Reynolds number(Re) and Relative Roughness parameter(ϵ/d) for fullydeveloped flows in a circular pipe.

It can be used to calculatethe Head loss $(h_f)$ through pipes for a given flow rate or …
