Answer 2

Given:

In a pipe of 360mm diameter having turbulent flow, the center-line is 7m/s, and that at 60 mm from the pipe wall is 6m/s.

Find:

Calculate the shear friction velocity.

Solution:

The speed at which the flow of water in a long cylindrical pipe of

diameter 2 cm becomes turbulent is

(The viscosity of water  $=1*10^{-3}$ Pa. s and for the onset of turbulent flow in a long cylindrical pipe, Reynolds number =3000)
