Torricelli law expresses that the speed of stream of liquid from a hole is equivalent to the speed that it would accomplish if falling unreservedly for a separation equivalent to the tallness of the free surface of the fluid over the opening .
The water won't fall in a parabola like a gun shot. The water won't go up and descend in light of the fact that this is an infringement of the protection of vitality as the work will be managed without the outer power to do chip away at it.
The condition of the speed is for the speed of the coming water independent of the introduction of the opening on the holder which is as an afterthought.
In any case, when the water is falling through the gap which is in the base of the holder. the water will turn out with consistent speed. Since the speed of the water isn't subject to the water section.

Hey mate,
◆ Torricelli law-
It states that the speed of flow of fluid from an orifice is equal to the speed that it would attain if falling freely for a distance equal to the height of the free surface of the liquid above the orifice.
◆ Experimental determination of speed of efflux-
Consider an ideal liquid of definite density contained in a tank provided with narrow hole at height h.
By Toriicelli's law, speed of the efflux is given by,
v = √(2gh)
Hope that was useful...
