Question

write an expression for the pressure at a point inside inside the liquid. explain the meaning of the symbols used.

Answer 1

P=pgh
where p is density of liquid
g is acceleration due to gravity
h is the height of point located below the liquid surface

Answer 2

The pressure at a point inside a liquid is given by:

P = Po + hpg

where,

• P is the point where pressure is exerted in the liquid
• Po is the atmospheric pressure
• h is the depth of the point below the free surface
• p is the density of the liquid
• g is the acceleration due to gravity.

hope it helps you...
