Side vessel has a small hole that cause leaking. The leaking hole is around $1m$ from the water surface at inside the vessel $($refer pic$)$:

Assume A$2($crossectional area point $2)/$A$1($crossectional area point $1)$ is very small which lead to velocity at point $1$ is neglible compare

with point $2$ based on continuity equation $A1V1=A2V2.$ In short, assume $V1=0$

What is the liquid velocity at point $2?$
