A denotes the area to the right on the cube

h

the depth of an orifice of area of cross-section

A

, below the liquid surface. The velocity of the liquid flowing through the orifice is

View answer and explanation

Correct option: B

\sqrt {2\mathrm{g}h} \sqrt {\left( {\frac{{{A^2}}}{{{A^2} - {a^2}}}} \right)}

Option B (

\sqrt {2\mathrm{g}h} \sqrt {\left( {\frac{{{A^2}}}{{{A^2} - {a^2}}}} \right)}

) is correct because it is derived from Bernoulli's theorem, accounting for the velocities at both the surface and the orifice.
