When a liquid in a container is subjected to rotation, its free surface deforms due to centrifugal forces. This phenomenon is commonly observed in rotating tanks, centrifuges, and even in a spinning glass of water.
Key Observations:
- The liquid level rises at the edges of the container and lowers at the center.
- The maximum rise at the container’s wall is determined by the rotational speed.
- The faster the rotation, the steeper the curvature of the paraboloid.
