Fluid Pressure & Depth – AP Physics 1

1. At 10 m depth in water (ρ=1000), gauge pressure is approximately:

1 atm (≈98 kPa) 2 atm 0.5 atm 10 atm

2. Pressure at a given depth depends on:

Container shape Fluid density and depth Container volume Surface area of fluid

3. Pascal's Principle states that pressure changes in a confined fluid are:

Absorbed by the walls Transmitted equally in all directions Only transmitted downward Reduced by half
