A tank containing liquid has an orifice in one vertical side. If the center of orifice is 19.6 m below the surface level in the tank. Find the velocity of discharge assuming that is no wastage of energy.

Question

A tank containing liquid has an orifice in one vertical side. If the center of orifice is 19.6 m below the surface level in the tank. Find the velocity of discharge assuming that is no wastage of energy. (A) 19.1 m / s (B) 20 m / s (C) 15 m / s (D) 9.8 m / s

Velocity at orifice =√2 gh =√2 × 9.8 × 19.6 =19.6 m / s

Q. A tank containing liquid has an orifice in one vertical side. If the center of orifice is $19.6 m$ below the surface level in the tank. Find the velocity of discharge assuming that is no wastage of energy.

$19.1 m / s$

$20 m / s$

$15 m / s$

$9.8 m / s$

Velocity at orifice
$= 2 g h = 2 \times 9.8 \times 19.6$
$= 19.6 m / s$
