The diagram shows a venturimeter through which water is flowing. The speed of water $$X$$ is $$2 \ \text{cms}^{-1}$$. The speed of water at $$Y$$ $$(\ taking\ g = 10 \text{ms}^{-2})$$ is

An ideal fluid is:

Water stored in a tank flows out through a hole of radius 1mm at a depth 10 m below the surface of water.The rate of flow of water in $$m^3 /s$$ will be

Bernoulli's equation includes as a special case:

Water flows steadily through a horizontal tube of variable cross-section. If the pressure of water is p at a point where the velocity of flow is v, what is the pressure at another point where the velocity of flow is 2v; $$\rho$$ being the density of water?

Two liquid jets coming out of the small holes at P and Q intersect at the point R. Find the position of R if we maintain the liquid level constant

A spherical ball falls through viscous medium with terminal velocity $$v$$. If this ball is replaced by another ball of the same mass but half the radius, then the terminal velocity will be (neglect the effect of buoyancy)

Water is filled in a container up to height $$3\ \text{m}.$$ A small hole of area '$$a$$' is punched in the wall of the container at a height $$52.5\ \text{cm}$$ from the bottom. The cross sectional area of the container is $$A.$$ If $$\dfrac{a}{A}=0$$; then $$v^2$$ is $$($$where $$v$$ is the velocity of water coming out of the hole$$)$$

In a horizontal pipeline of uniform cross section the pressure falls by $$8N/m^2$$ between two points separated by 1 km. If oil of density $$800 kg/m^3$$ flows through the pipe, find the change in KE per kg of oil at these points.

A pressure meter attached to a closed water tap reads $$1.5\times 10^5\ \text{Pa}$$. When the tap is opened, the velocity of flow of water is $$10\ \text{ms}^{-1}$$ and the reading of the pressure meter is
