The velocity of water in a rier is `18kmh^-1` near the surface. If the river is 5 m deepm, find the shearing stress between the horizontal lyers of water. The coefficient of viscosity of water `=10^-2 poise.

The velocity of water in a river is 72 km h^(-1) near the surface. If the river is 4 m deep, find the shearing stress between horizontal layers of water. Coefficient of viscosity of water = 0.01 poise.

The velocity of water in a river is 18 km/h near the upper surface. The river 5 m deep. What is the shearing stress between the horizontal layers of water ? (Coefficient of viscosity of water= 10^(- 2) Poise)

The velocity of water in river is 180 km h^(-1) near the surface .If the river is 5 m deep,then the shearing stress between the surface layer and the bottom layer is ( cofficient of viscosity of water eta =10^(-3) Pa s)

The velocity of water near a river's surface is 20 km/hr. If the depth of the river is 4 m, calculate the shearing stress between the horizontal layers of water. Take, coefficient of viscosity of water = 0.01 poise.

The velocity of water in a river is 18 kmph near the surface. If the river is 4 m deep, the shearing stress between horizontal layers of water in Nm^(-2) is (eta_("water")=1xx10^(-3)pa.s)

The velocity of water in a river is 2ms at the surface.If the river is 2m deep the shearing stress between the horizontal layers of water assuming bottom layer at rest ( eta=10^(-3) S I units for water)

A river 10 m deep is flowing at 5ms^(-1) . The shearing stress between horizontal layers of the rivers is ( eta=10^-(3) SI units)

The velocity of water in river is 9 km/h of the upper surface . The river is 10 m deep . If the coefficient of viscosity of water is 10^(-2) poise then the shearing stress between horizontal layers of water is

What is the force due to viscosity acting on a layer of water of area 4xx10^(-2)m^2 , if the relative velocity between the two layers of water, separated by 0.4 mm is 5 cm/s ? The coefficient of viscosity of water = 0.01 poise.[1 poise=0.1 Ns//m^2 ]

A boat of area 10m^(2) floating on the surface of river is made to move horizontally with a speed of 2m/s by applying a tangential force. If the river is 1 m deep and the water in contact with the bed is stationary, find the tangential force needed to keep the boat moving with constant speed. ("coefficient of viscosity of water "=10^(-2)" poise")
