Question

The level of water in a tank is 5 m high. A hole of the area 10 c m 2 is made in the bottom of the tank. The rate of leakage of water from the hole is, 10 - 2 m 3 s - 1, 10 2 m 3 s - 1, 10 m 3 s - 1, 10 -4 m 3 s - 1

MARKS App · Accepted Answer

The velocity of efflux, v = 2 gh ; The volume of liquid flowing out per second = v × A = 2 gh × A = 2 × 10 × 5 × 10 × 10 - 4 = 10 - 2 m 3 s - 1
