Question
A smooth pipe of 100 mm diameter and 1000 m long is carrying water at the rate
of 10 litres/sec. If the kinematic viscosity of water is 0.015 stokes and the value of
where Re is Reynolds
0.0623
co-efficient of friction 'f' is given by the relation f =
(Re)1/4
number, calculate:
(1) Loss of head,
(2) Wall shearing stress,
(3) Centre-line velocity,
(4) Velocity and shear stress at 20 mm from the pipe wall, and
(5) Thickness of laminar sublayer.
