Question

Give an example of a hydrostatic pressure gradient that is negative.

Answer 1

Negative hydrostatic pressure:

1. Negative hydrostatic pressure occurs when a force is exerted in the opposite direction of gravity.
2. This pressure fluctuates depending on the length of the fluid-filled tube, the density of the fluid, and the effect of gravity.
3. Hydrostatic pressure gradient refers to a pressure variation caused by depth.

Example:

1. A suction via a straw is an example of a negative hydrostatic pressure gradient.
