List of top Physics Questions on mechanical properties of fluid asked in AP EAPCET

A large tank filled with water to a height \(h\) is to be emptied through a small hole at the bottom. The ratio of times taken for the level of water to fall from \(h\) to \(\frac{h}{2}\) and from \(\frac{h}{2}\) to zero is
A capillary tube of inner radius 1.5 mm is dipped vertically in water. If the surface tension of water is \( 7 \times 10^{-2} \text{ Nm}^{-1} \), then the volume of the water that rises in the capillary tube is (\( g=10 \text{ ms}^{-2} \)):
A long cylindrical vessel of glass having a hole of 0.5 mm radius at its bottom is slowly lowered vertically into a deep water bath. If the surface tension of water is \( 7 \times 10^{-2} \, Nm^{-1} \) then the maximum depth the vessel can be submerged without water entering through the hole is: (Acceleration due to gravity \( = 10 \, ms^{-2} \))
A metallic wire of density $\rho$ is placed horizontally on the surface of a liquid with surface tension $T$. What is the maximum radius the wire can have so that it remains supported by surface tension?
Calculate the amount of work done in spraying a drop of a liquid of radius 1 mm into million identical droplets under isothermal conditions. [surface tension of liquid $=550\times10^{-3}\text{Nm}^{-1}$]
A liquid rises to a height of $4 \text{ cm}$ in a capillary tube of radius $r$. If another capillary tube of radius $r/2$ is dipped in the same liquid, the height of liquid rise will be
The rate of flow of a liquid through a capillary tube of radius $r$ and length $l$ under a pressure difference $P$ is proportional to
A soap bubble of radius $1$ cm has surface tension $0.03$ N/m. Excess pressure inside is:
