Torricelli's Law

Torricelli's Law states that the speed of fluid flowing out of a hole in a container is determined by the height of the fluid above the hole. Specifically, the speed is proportional to the square root of the height; higher fluid levels mean faster outflow. This principle explains why water drains quickly from a full tank compared to a nearly empty one. The law is often used in physics and engineering to calculate flow rates in various applications, including plumbing and hydraulic systems, highlighting the relationship between pressure, gravity, and fluid motion.
