Definition of Pressure variation with depth in a fluid
Check what you remember
Read the wording for your board, then hide it and explain Pressure variation with depth in a fluid in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
In a fluid at rest, pressure increases with depth according to p = ρgh, where ρ is the fluid density, g is the gravitational field strength and h is the depth below the surface.
