Question

define fluid pressure derive an expression for pressure at a point inside a liquid​

Answer 1

The answer is given below.

What is Fluid pressure:

• The force per unit area acting on an item submerged in fluid or on the surface of a closed container is measured as fluid pressure.

• Gravity, acceleration, or external forces may all contribute to this pressure in a closed container. A fluid has no fixed shape, hence its pressure is uniform throughout.

Derivation of expression for pressure inside a liquid:

• In a liquid, the pressure at a certain place is determined by:

• $P=P_{0} +hpg$

• Where P is the location where the liquid is under pressure.

• $P_{0}$ is the atmospheric pressure

• H stands for the point's depth below the free surface.

• P is the liquid's density, and G is the acceleration brought on by gravity.
