As the depth of the river increases, the velocity of flow

Velocity of a swimmer with respect to a river is (hat i+4hat j)m/s and velocity of the river flow is (2hat j)m/s then velocity of swimmer with respect to ground is (in m/s)

A man who can swin at the rate of 2 (km)/hr) (in still river) crosses a river to a point exactly opposite on the other bank by swimming in a direction of 120^@ to the flow of the water in the river. The velocity of the water current in (km)/(hr) is

A man who can swin at the rate of 2 (km)/hr) (in still river) crosses a river to a point exactly opposite on the other bank by swimming in a direction of 120^@ to the flow of the water in the river. The velocity of the water current in (km)/(hr) is

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.

A pitot tube dipped in a river and its gauge indicates 5cm of water column .What is the velocity of flow of water in the river?

A man wishes to cross a river flowing with velocity u swims at an angle theta with the river flow.If the man swims with speed v and if the width of the river is d , then the drift travelled by him is

A river of width 80m is flowing at 6 m/s. A motorboat crosses the river in 10s and reaches a point directly across on the other river bank. The velocity of motorboat in still water is :
