"Connector" Pressure and Buoyancy PPT Courseware 3

Description

"Connector" Pressure and Buoyancy PPT Courseware 3

1. Connector

1. A container with an open upper end and a connected lower end is called a connector.

2. Features of the connector:

When the same liquid in the connector is at rest, the liquid levels in each container remain level.

Analysis: As shown in the figure, imagine that there is a small liquid piece AB at the bottom of the connector. To make AB immobile, the pressure on both sides of AB must be equal, and only when the heights of the water columns on both sides are equal, their pressures on AB can be equal.
