List of top Physics Questions on mechanical properties of fluid asked in AIIMS

An object floats in water with 10% of its volume outside and in oil 30% of its volume outside. The specific gravity of the oil is

Surface tension decreases with increases in temperature. On increasing temperature kinetic energy increases and intermolecular forces decreases..

Water is flowing with velocity $4 \,m\,s^{-1}$ in a cylinder of diameter $8\,cm$, it is connected to a pipe with it end tip of diameter $2\,cm$, calculate the velocity of water at this free end.

Two spherical soap bubbles of radii $a$ and $b$ in vacuum coaleasce under isothermal conditions. The resulting bubbles has a radius given by

A liquid is kept in a cylindrical vessel which is being rotated about a vertical axis through the centre of the circular base. If the radius of the vessel is $r$ and angular velocity of rotation is $\omega$, then the difference in the heights of the liquid at the centre of the vessel and the edge is

A capillary tube of radius $r$ is immersed in water and water rises in it to a height $h$. The mass of water in the capillary tube is $5\,g$. Another capillary tube of radius $2\,r$ is immersed in water. The mass of water that will rise in this tube is

Neglecting the density of air, the terminal velocity obtained by a raindrop of radius $0.3\, mm$ falling through air of viscosity $1.8 \times 10^{-5}\, N \,s \,m ^{-2}$ will be

By sucking through a straw, a student can reduce the pressure in his lungs to $750\, mm$ of $Hg$ (density $= 13.6\, g/cm^3$ ). Using the straw, he can drink water from a glass upto a maximum depth of

A thin stainless steel needle can lay floating on a still water surface. Any object floats when the buoyancy force balances the weight of the object.

Specific gravity of a fluid is a dimensionless quantity. It is the ratio of density of fluid to the density of water.

A candle of diameter $d$ is floating on a liquid in a cylindrical container of diameter $D (D > > d)$ as shown in figure. If it is burning at the rate of $2$ cm/hour then the top of the candle will

Smaller drops of liquid resist deforming forces better than the larger drops. Excess pressure inside a drop is directly proportional to its surface area.

A sphere of mass $M$ and radius $R$ is falling in a viscous fluid. The terminal velocity attained by the falling object will be proportional to

Bernoulli's equation is a consequence of conservation of

A lead shot of $1\, mm$ diameter falls through a long column of glycerine. The variation of its velocity $v$ with distance covered is represented by

For liquid to rise in a capillary tube, the angle of contact should be

When a large bubble rises from the bottom of a lake to the surface, its radius is doubled. The atmospheric pressure is equal to that of a column of water of height $H$. The depth of the lake is
