A cylindrical vessel of radius $R$ and height $H$ and open at the top is completely filled with water. A small circular hole of radius $r$ is made near the bottom of vessel. The time taken for $25 %$ of water to flow out is

Options:

Answer:

Solution:

$T = \frac{A}{a} \sqrt{\frac{2 H}{g}} = \frac{R^{2}}{r^{2}} \sqrt{\frac{2 H}{g}}$
$t_{1} = \frac{R^{2}}{r^{2}} \sqrt{\frac{2}{g} \times (\frac{3 H}{4})}$
$∴ Δ t = T - t_{1} = \frac{R^{2}}{r^{2}} \sqrt{\frac{2 H}{g}} (1 - \frac{\sqrt{3}}{2})$
