Torricelli's velocity of efflux is $v = 2 g h$ , where $h$ is the height of the liquid above the hole. After leaving the hole, treat the flow as projectile motion.
The two vessel configurations (i) and (ii) are shown below.

What is its time of fall of liquid on the ground?

Options:

Answer:

Solution:

The outlet is $H = 2 sin 3 0^{\circ} = 1 m$ above ground.
For horizontal efflux, vertical motion starts from rest.
Thus $H = \frac{1}{2} g t^{2}$ .
Hence $t = 2 H / g = 1/ 5 s$ for $g = 10 m/ s^{2}$ . Answer: C.
