A ball of weight `W` is supported on a vertical jet of water. If the stream of water flowing from the nozzle has a diameter `D` and velocity `u`, determine the value of `H`. Assume that no loss of energy takes place.

If a small ping pong ball is placed in a vertical jet of water or air, it will rise to a certain geight above the nozzle and will be spinning there.

A water bgarrel having water up to a depth d is placed on a table of height H. A small hole is made on the wall of the barrel at its bollom. If the stream of water comiong out of the hole falls on the ground at a horizontal distance r from the barrel, then the value of d is

A vertically jet of water coming out of a nozzle with velocity 20 m//s supports a plate of mass M stationary at a height h = 15 m , as shown in the figure. If the rate of water flow is 1 litre per second, the mass of the plate is (Assume the collision to be perfectly inelastic).

The figure shows the commonly observed decrease in diameter of a water stream as it falls from a tap. The tap has internal diameter D_(0) and is connected toa large tank of water. The surface of the water is at a height b above the end of the tap. By considering the dynamics of a thin "cylinder" of water in the steam answer the following: (ignore any reistance to the flow and any effects of surface tansion, given rho_(w) = density of water) Equation for the stream diameter D in terms of x and D_(0) will be :
