Bernoulli's Principle and its Applications

A siphon tube is used to carry water from a reservoir at a pressure greater than atmospheric pressure to an open-end $4 \text{m}$ below the water surface. If the summit of the siphon is at $1 \text{m}$ height, calculate the speed of water coming out of the open end in $\text{m/s}$. Take the value of $g=10 {\text{m/s}}^2$ and consider summit of the siphon to be at atmospheric pressure.

What is a siphon? On what principle does it work? List some of its applications.

Briefly describe the working of a siphon.

The pressure at the sumit of a siphon is

Which one of the following theories can be used to explain the working of a siphon?

What is pitot tube?

Explain one application of magnus effect.

A closed vessel have a small hole in one face of vessel near the bottom as shown. The velocity (in $\mathrm{m} {\mathrm{s}}^{-1}$) of water coming out from the given hole at given instant is :

Water is filled in a cylindrical container to a height of $3 \mathrm{m}.$ The ratio of the cross-sectional area of the orifice and the beaker is $0.1.$ The square of the speed of the liquid coming out from the orifice is $\left(g=10 \mathrm{m} {\mathrm{s}}^{-2}\right).$

A water tank is filled upto height $h$ and is being emptied through a small hole at the bottom. Ratio of time taken for the level of water to fall from $h$ to $\frac{h}{2}$ and from $\frac{h}{2}$ to zero is (take $\sqrt{2}=1.41$)

Figure shows two holes in a wide tank containing a liquid column. The water streams coming out of these holes strike the ground at the same point. The height of liquid column in the tank is :-
