Conservation of mass (a.k.a., continuity) [Fluid Mechanics #2]

In this video, we start exploring the conservation laws of fluid mechanics---a set of equations that define how fluids move and respond to force.

Our first step is to build the Conservation of Mass, a.k.a. Continuity. In observing a fluid through an observation window, if mass flows in it either must flow out or our window's mass changes. We build the balance of mass equation and consider the incompressible assumption, meaning we can't change the fluid density. By the end of the video, you should have a better physical intuition of what mass conservation means for a fluid.
