Question

A cylinder of height 20 m is completely filled with water. The velocity of efflux of water (in ms -1 ) through a small hole on the side wall of the cylinder near its bottom is (A) 10 (B) 20 (C) 25.5 (D) 5

Tardigrade Admin · Accepted Answer

According to Torricelli's theorem, the velocity of efflux of water, v=√2 g h=√2 × 10 × 20=20 ms -1.

According to Torricelli's theorem, the velocity of efflux of water,
$v = 2 g h = 2 \times 10 \times 20 = 20 m s^{- 1}$ .
