List of top Physics Questions on Bernauli Theorem

Water is flowing through a horizontal tube having cross-sectional areas of its two ends beings $A$ and $A$' such that the ratio $A/A$' is $5$. If the pressure difference of water between the two ends is $3 \times 10^5\, N m^{-2}$, the velocity of water with which it enters the tube will be (neglect gravity effects)

In a u-tube as shown in figure, water and oil are in the left side and right side of the tube respectively. The heights from the bottom for water and oil columns are 15 cm and 20 cm respectively. The density of the oil is :- [take \(\rho_{water}\) = 1000 kg/m\(^3\)]

A cylinder of height 1m is filled with water. If a small orifice is made at a height of 0.25 m from the ground, the horizontal range of water stream will be :

There are two identical small holes on the opposite sides of a tank containing a liquid. The tank is open at the top. The difference in height between the two holes is $h$. As the liquid comes out of the two holes, the tank will experience a net horizontal force proportional to

The velocity of efflux of a liquid through an orific in the bottom of the tank does not depend upon

Pressure head in Bernoulli's equation is

According to Bernoullis equation $ \frac{P}{\rho g}+h+\frac{1}{2}\frac{{{v}^{2}}}{g}=\text{constant} $ The terms A, B and C are generally called respectively:

A rectangular vessel when full of water, takes $10$ minutes to be emptied through an orifice in its bottom. How much time will it take to be emptied when half filled with water ?

Aerofils are so designed that the speed of air:

A hole is in the bottom of the tank having water. If total pressure at the bottom is $3$ atm $(1 \,atm = 10^{5}\, Nm^{-2})$, then velocity of water flowing from hole is

A thread is tied slightly loose to a wire frame as in figure and the frame is dipped into a soap solution and taken out. The frame is completely covered with the film. When the portion $A$ is punctured with a pin, the thread ..........

Scent sprayer is based on

Water flows through a horizontal pipe of diameter $2 \,cm$ at a speed of $3 \,cm \,s^{-1}$, The pipe has a nozzle of diameter $0.5 \,cm$ at its end. The speed of water emerging from the nozzle is

Torricelli?? barometer used mercury but Pascal duplicated it using French wine of density $ 984 \,kg \,m^{-3} $ . In that case, the height of the wine column for normal atmospheric pressure is (Take the density of mercury $ = 13.6 \times 10^{3} \,kg\, m^{-3} $ )

There are two holes one each along the opposite sides of a wide rectangular tank. The cross section of each hole is $0.01\,m^2$ and the vertical .distance between the holes is one meter. The tank is filled with water. The net force on the tank in New ton when water flows out of the holes is : (Density of water $1000kg/m^3)$

The velocity head of a stream of water is 40 cm. Then, the velocity of flow of water is

The probability of safe arrival of one ship out of five is $\left(\frac{1}{5} \right)$ . The probability of safe arrival of atleast 3 ship is:

The probability of getting at least 2 heads, when an unbiased coin is tossed 6 times is

The dynamic lift of an aeroplane is based on
