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)
