Torricelli's law is a principle in fluid dynamics that describes the speed of fluid flowing out of an orifice under the influence of gravity. It states that the speed (velocity) \\( v \\) of a fluid flowing out of an opening at the bottom of a tank is proportional to the square root of the height \\( h \\) of the fluid above the opening.
