Question

A point is ' $h$ ' metre below the surface of a liquid of density $\rho$. If $\mathrm{P}_0$ is atmospheric pressure, the absolute pressure a that point is

Professor PC Thomas Classes · Answer

The absolute pressure at a depth $h$ in a liquid of density $\rho$ is the sum of the atmospheric pressure and the pressure due to the liquid column. Absolute pressure = $P_0 + h\rho g$.
