Hydrostatic pressure equation:
In a static fluid of uniform density

\(\rho\), the hydrostatic pressure exerted at a vertical depth \(h\) below the free surface is given by the fundamental hydrostatic equation: \[P = \rho g h = \gamma h\]

where:

• \(\rho\) = fluid mass density (\(\text{kg/m}^3\))
• \(g\) = acceleration due to gravity (\(9.81\text{ m/s}^2\)) - \(h\) = fluid depth / head (m) - \(\gamma = \rho g\) = specific weight of fluid (\(\text{N/m}^3\))
