Water flows through a frictionless duct with a crosssection varying as shown in fig. Pressure p at points along the axis is represented by 

For a fluid which is flowing steadily, the level in the vertical tubes is best represented by 

A common hydrometer has a long uniform stem. When floating in pure water, 4.5 cm of its stem lies below the surface of water. In a liquid of specific gravity 2.0, 1.5 cm of the stem of the same hydrometer is immersed. Find the specific gravity of the liquid in which the hydrometer is immersed upto 0.5 cm.

The height of mercury which exerts the same pressure as 20 cm of water column is :( Given relative density of mercury=13.56)

Two identical cylindrical vessels with their bases at the same level; contain liquid of density $$\rho$$. The area of both is $$S$$, but the height of liquid in one vessel is $${h}_{1}$$ and in other $${h}_{2}$$. The work done when both cylinders are connected, by gravity in equalising levels is:

The pressure of gas in a metal cylinder is 4 atmospheres at $$27 C$$, then the pressure at $$54 C$$: (in atmosphere)

A container is filled with water to a height of 10 m. The pressure exerted by the water at the bottom of the container is _____ Pa.

The pressure exerted by a liquid column at the bottom of the container at a point inside a fluid

The height of mercury which exerts the same pressure as 20 cm of water column, is_____

Two capillary tubes of diameters 3.0 mm and 6.0 mm are joined together to form a U-tube open at both ends. If the U-tube is filled with water, what is the difference in its levels in the two limbs of the tube? Surface tension of water at the temperature of the experiment is $$7.3 \times 10^{-2} N/m$$. Take the angle of contact to be zero and density of water to be $$10^3 kg/m^3(g = 9.8 m/s^2)$$
