Pressure Due to a Liquid (Leaving Cert Physics): Flashcards

$P = \rho gh$

Pressure (Pa)

Density (kg/m³)

Gravity (9.8 m/s²)

Height/depth of liquid (m)

Pascal (Pa)

Increases linearly with depth

Same in all directions

Density, depth, gravity

No

$P_2 - P_1 = \rho gh$

Pressure difference with depth

Pressure increases with depth

Force per unit area from liquid
