ρ of water (kg/m³)
1. Formula
P = ρ g h
ρ = density, g = 10 m/s², h = depth
unit: pascal (Pa) = N m⁻²
2. Facts
• Lowest hole: the strongest jet
• Same pressure in every direction at the same depth
• Pressure does not depend on the shape of the tank
3. Remember
A dam wall is made thicker at the bottom
The deeper the diver, the greater the pressure
