This is a key characteristic of static pressure. It's the pressure exerted by a fluid at rest, and it acts equally on all surfaces in contact with the fluid.

Here's a simple analogy: Imagine a balloon filled with air. The air inside exerts pressure on the balloon's surface, pushing outwards in every direction, causing the balloon to inflate. This pressure is static pressure.

In contrast, dynamic pressure is associated with the motion of a fluid and acts in the direction of flow.
