Title: Demonstration of an incompressible flow Description: The continuity equation (nabla u = 0, or div u = 0) implies that a flow is incompressible. This condition usually applies to most liquids, such as water. This recording, done with a high-speed camera at 3000 fps, demonstrates this relationship using a simple liquid, a plastic cup and a large weight (with augmentation by Richard Strauss).
