3 answers

Priyesh Saxena 5 years, 3 months ago

Depth and density

Siya Mandhan 5 years, 3 months ago

Pressure within a liquid depends only on the density of the liquid, the acceleration due to gravity and the depth within the liquid. The pressure exerted by such a static liquid increases linearly with increasing depth.

Yogita Ingle 5 years, 3 months ago

The pressure exerted by the liquid depends on that body depends on:

The depth of body: The depth of the body at which the pressure of the liquid is acting on the body. Deeper the body, higher would be the extent of the pressure of liquid acting on the body.
The density of liquid: The pressure of liquid acting on any particular body hugely depends upon the density of the liquid (the physical quantity depending on the mass-volume ratio). Higher the density, higher would be the pressure of liquid acting on the body in contact with that liquid
