Real-Life Context: Torricelli’s theorem applies Bernoulli’s principle to calculate the speed of fluid flowing out of a small hole in a container, like water draining from a punctured bottle, a leaking tank, or even in fire hoses. It’s used in engineering for tank drainage times, irrigation systems, and understanding fluid jets.

How to Interact: Adjust the sliders for fluid depth \( h \) (above the hole) and gravity \( g \). Watch the water jet animate with a parabolic trajectory, see the efflux velocity update, and observe the energy terms in the bar chart.
