Calcolatrice Pressione Idrostatica — Formula
## Hydrostatic Pressure
Pressure in a static fluid increases linearly with depth due to the weight of the fluid above.
### Formula
**P_gauge = rho g h**
**P_absolute = P_atm + rho g h**
where rho is fluid density, g = 9.81 m/s^2, and h is the depth below the free surface. For water, pressure increases by approximately 9.81 kPa (about 1 atmosphere per 10.33 m) for each metre of depth.

Esempio Risolto
10 m below the surface of fresh water at standard atmospheric pressure.
- Gauge pressure = 1000 x 9.81 x 10 = 98,100 Pa = 98.10 kPa
- Absolute pressure = 101.325 + 98.10 = 199.43 kPa
- This is approximately 2 atmospheres absolute.
