MathLiveHydrostatic pressure difference
This gives the pressure difference between two points in a fluid at rest, which equals the fluid density times gravitational acceleration times the vertical depth difference. It is used to calculate pressure in liquids such as water in tanks, dams, and manometers, and it is the working form of Pascal's law for static fluids.
\Delta p = \rho g \Delta hWhat the symbols mean
| pressure difference between two points (Pa) | |
| mass density of the fluid (kg/m^3) | |
| gravitational acceleration (m/s^2) | |
| vertical depth difference between the two points (m) |
