In a cylindrical vessel containing liquid of density $$p$$, there are two holes in the side wall at heights $$h_{1}$$ and $$h_{2}$$ respectively such that the range of efflux at the bottom of the vessel is same. The height of a hole, for which the range of efflux would be maximum, will be:

At $$20^{o} $$C, to attain the terminal velocity how fast will an aluminium sphere of radii $$1\ mm$$ fall through water. Assume flow to be laminar flow and specific gravity $$(Al)-2.72$$

Water flows through a horizotal pipe of varying cross-section. The pressure of water equals to 0.1 m of mercury at a place where the velocity of flow is 0.4 $$ms^{-1}$$. What will be the pressure at another place where the velocity of flow is 0.5 $$ms^{-1}$$?

Water flows in a streamline manner through a capillary tube of radius a. The pressure difference being P/2 and the rate of flow is 8 cc per second. If the radius is reduced to r/2 and the pressure is increased to P, then the rate of flow becomes

Two equal spherical bodies A and B specific gravity $$1.2$$ and $$0.8$$ respectively are attached by a thin mass less rod. Now it is placed inside the water as shown in the figures. The bodies A and B are in

A vision liquid flows through a horizontal pipe of varying cross-sectional area. Identify the option which correctly represents the variation of height of rise of liquid in each vertical tube 

A wooden cylinder of diameter $$4r$$, height $$h$$ and density $$\rho /3$$ is kept on a hole of diameter $$2r$$ of tank, filled with liquid of density $$\rho$$ as shown in the figure.
Now level of the liquid starts decreasing slowly. When the level of liquid is at a height $${h}_{1}$$ above the cylinder the block starts moving up. At what value of $${h}_{1}$$, will the block rise?

Bernoulli's equation is applicable to

A metal ball is being weighed in a liquid whose temperature is raised continuously. Then the apparent weight of the ball :

When a pipe of the radius of cross- section '$$r$$' is arranged at a height h horizontally the jet of from it touches at a distance '$$x$$' from a point just below the pipe on the ground. if the pipe is closed partly such that its radius of cross-section becomes $$r/2$$ and it is arranged at a height $$4h$$ then the horizontal distance at which waterfall increases by
