Pitot tube is used to measure _____ flows in different industries.

Pitot tube is used to measure speed of an aircraft.

What is pitot tube?

A non-spinning ball is not subjected to the Magnus effect. This Magnus effect is equivalent to : 

Which of the following forces are acting on a non-spinning ball during its flight:

Motion of ball without spin in air follow the path

Motion of ball with spin in air follow the path

Potential energy term of Bernoulli's equation is not considered for its application in:

The potential energy term in Bernoulli's equation is present due to:

Bernoulli's theorem is a restatement of :

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 pipeline has its two ends with areas of cross section as $20 {\mathrm{cm}}^2$ and $10 {\mathrm{cm}}^2$ respectively. Consider a steady flow of water in the pipeline such that, the velocity of flow and the pressure at the larger opening is $2 \mathrm{m} {\mathrm{s}}^{-1}$ and $9000 \mathrm{Pa}$ respectively. What is the pressure at the smaller opening? (use density of water $={10}^3 \mathrm{kg} {\mathrm{m}}^{-3}$)

The velocity at which the water emerge from an orifice in a tank in which gauge pressure is $3\times {10}^5 {\mathrm{N}\mathrm{m}}^{-2}$ before the flow starts is ____ (Take the density of water = $1000\mathrm{ }\mathrm{k}\mathrm{g}\mathrm{ }{\mathrm{m}}^{-3})$ .

A large open tank has two holes in the wall. One is a square hole of side L at a depth y from the top and the other is a circular hole of radius R at a depth 4y from the top. When the tank is completely filled with water, the quantities or water flowing out per second from the two holes are the same. Then, the value of R is

Toricelli's theorem is used to find:

When a train crosses a platform with high velocity, passenger on the platform tend to fall towards the train. This phenomenon can be explained on the basis of:

A tank is filled with water to a height H. A hole is punched in one of the walls at a depth h below the water surface. Then the distance x from the foot of the wall at which the stream strikes the floor is -

A liquid having area of free surface $\mathrm{\prime }\mathrm{A}\mathrm{\prime }$ has an orifice at a depth $\mathrm{\prime }\mathrm{h}\mathrm{\prime }$ with an area $\mathrm{\prime }\mathrm{a}\mathrm{\prime }$ below liquid surface, then the velocity $\mathrm{V}$ of flow through the orifice is -
