The level of water in a tank is 5m high. A hole of area 1cm 2 is made at the bottom of the tank . The rate of leakage of water from the level is (g=10 m/s 2 ).
Speed of Efflux.But hereSince the diameter of tank isn't given.Arun KumarIIT DelhiAskiitians Faculty
sir what is A2 and A1
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)
