A small hole of area cross-section $2 m m^{2}$ is present near the bottom of a fully filled open tank of height $2 m .$ Taking $g = 10 m s^{- 2}$ , the rate of flow of water through the open hole would be nearlyNEET 2019 (All India)

Options:

Answer:

Solution:

Velocity of efflux $v = \sqrt{2 g h}$
$v = \sqrt{2 \times 10 \times 2}$
$= 2 \times \sqrt{10}$
Rate of flow $=$ area $\times v$
$= 2 \times 10^{- 6} \times 2 \times \sqrt{10}$
$= 4 \times 3.14 \times 10^{- 6}$
$≅ 12.6 \times 10^{- 6}$
