hydrostatic pressure

Question

Pressure at depth h in fluid density ρ (neglect variation) is:

RankGuru · Accepted Answer

Hydrostatic stress (pressure) increases with depth due to the weight of the fluid column above. For an incompressible fluid:
$P = P_{above} + \rho g h$
- If we consider the pressure relative to the surface (gauge pressure), it is simply $P = \rho g h$.
- $\rho$: Fluid density
- $g$: Acceleration due to gravity
- $h$: Depth below the surface
This law forms the basis for Pascal's principle and the operation of hydraulic systems.
