Question

Q. An oil of 8 poise and specific gravity 0.9 is flow-
ing through a horizontal pipe of 50 mm diameter.
If the pressure drop in 100 m length of the pipe
is 2000 kN/m², determine: (i) Rate of flow of oil
(ii) Centre-line velocity; (iii) Total frictional drag
over 100 m length of pipe; (iv) Power required
to maintain the flow; (v) Velocity gradient at the
pipe wall; (vi) Velocity and shear stress at 10 mm
from the wall.
