Fluid dynamics

Question

For the area a of the hole is much lesser than the area of the base of a vessel of liquid, velocity of effiux v of the liquid in an accelerating vessel is:

Moderate

A

$\sqrt{2 gh}$
B

$\sqrt{2 | g - a_{0} | h}$
C

$\sqrt{2 (g + a_{0}) h}$
D

none of these

Solution

Effective value of acceleration due to gravity becomes (g+ $a_{0}$ ).
$V = \sqrt{2 g_{eff} h} = \sqrt{2 (g + a_{0}) h}$
