AP Physics 1 & 2 Continuity Equation for Fluids
III. Fluids: Lecture 3 | 7:00 min
This is a relatively short yet important topic. The continuity equation basically states that fluids travel at a constant rate, and are mass-conserving. A fluid will travel slower through a larger hole and faster through a smaller in order to conserve the volume of the fluid thats displaced. If the fluid has uniform density, then mass is also conservatively displaced. This is much like Pascals Principle where itll be a very useful equation in determining aspects of one part of a system if you know another.
