Hydrostatic pressure is calculated using which formula?

Hydrostatic pressure is defined as the pressure exerted by a fluid at equilibrium due to the gravitational force acting on that fluid. The formula that accurately represents this relationship is P = mgh, where P is the pressure, m is the mass of the fluid, g is the acceleration due to gravity, and h is the height of the fluid column above the point in question.

Hydrostatic pressure increases with the depth of the fluid, which is directly related to the height (h) of the fluid column. The weight of the fluid (W) can be expressed as the mass (m) times gravity (g), allowing for the substitution and derivation of pressure in terms of height.

The other formulas mentioned do not specifically pertain to hydrostatic pressure. The formula P = F/a describes pressure in general as force per unit area, but it does not account for the specific gravitational aspect of liquids. P = MV defines momentum rather than pressure. P = W/F establishes a relationship between work and force, which is not relevant to hydrostatic pressure calculations. Therefore, the correct formula to calculate hydrostatic pressure is P = mgh, capturing both the gravitational effects and the fluid's characteristics.
