Speed of Efflux.

$v=\sqrt{2g\Delta h}/(1-(A_{2}/A_{1})^2)$

But here

$A_{2}<<A_{1}$

Since the diameter of tank isn't given.

$v=\sqrt{2g\Delta h} \\=>v=10m/s$

The hole made at the bottom of a tank resembles an orifice and according to Toricelli’s Theorem,

The velocity of an efflux = (2gh)^½= (2x10x5)^1/2 = 10 m/s.

Rate of leakage = Velocity x Area = 10 x 10^-4= 10^-3 m³/s.

(Note that the area has been converted from cm² to m² to provide the answer in SI units)
