The velocity of water in a river is $\displaystyle 18$ km/hr near the surface. If the river is $\displaystyle 5$ m deep , find the shearing stress between the horizontal layers of water. The co-efficient of viscosity of water $\displaystyle =10^{-2}$ poise.
Official answer
(3)
$\displaystyle 10^{-3} \mathrm{~N} / \mathrm{m}^2$
