Check the correction of the equation p=phg, where p= pressure at a point h below the free surface of the liquid of density p and g as the acceleration due to gravity.with method
The equation p = phg is correct.
This equation represents the pressure at a point h below the free surface of a liquid of density p and gravity g. The pressure at a certain depth h in a liquid is given by the product of the density of the liquid, the acceleration due to gravity, and the depth h.
Therefore, the equation p = phg accurately represents the pressure at a point h below the free surface of the liquid.
