A river of salty water is flowing with a velocity 2 `ms^(-1) `  If the density of the water is 1.28 c `c^(-1)`, then the kinetic momentum during a collision, the condition is energy of each cubic meter of water is

A river of salty water is flowing with a velocity 2m//sec . If the density of water is 1.2 gm//c c , the kinetic energy of each of cubic metre of water is

Velocity of flow of water in a horizontal pipe is 4.9 ms^(-1) Find the velocity heat of water.

A river water is flowing at 5ms^-1 . The depth of river water is 10m. What is the shearing stress between horizontal layers of the river water? Viscosity of water is 1 mili decapoise.

A person rows a boat in a water with a speed of 4 ms^(-1) . Water in the river is flowing with a speed of 2 ms^(-1) . If the person rows the boat perpendiculat to thedirection of flow, find resultant velcity of the boat and time taken by boat to cross the river if widthe of the river is 400 m .
