Answer / nader moustafa

The question is not fully clear Reynold number is define as
the R= VD/kinamatic viscosity . where V is the mean
velocity and D is the pipe inner diameter. Reynolds is used
for many purposes in fluid mechanics one of them is the
determination of friction factor. As mentioned in Answe
one. It is true that f=64/Re for laminar flow. Whereas for
turbulent flow coleebrook eqation should be used
