Question

Write the factors on which liquid pressure depends.

Answer 1

The pressure at a point in a liquid depends on the following factors:

1. Height of the liquid column ($h$): the pressure due to a liquid at a point inside the liquid increases with the height of the liquid column above that point.
2. The density of the liquid ($\rho$): the pressure due to a liquid is directly proportional to its density, the greater the density of the liquid more is the pressure exerted by it.
3. Acceleration due to gravity ($g$): the pressure due to a liquid at a point inside the liquid increases with the acceleration due to gravity at that point.

Mathrmatically, pressure $P=\rho gh$.
