Hydrostatic pressure
The deeper you go, how does the force from the liquid change?
The pressure produced by a liquid is proportional to the liquid's density and the depth, and does not depend on the container's shape or the sensor's area. At the same depth, enlarging the horizontal sensor leaves the pressure unchanged but increases the force exerted by the liquid.
Gauge pressure vs. depth
Think about it
Keeping the depth constant, if the sensor area is doubled, how do the pressure and the force each change?
The pressure stays the same and the force doubles. Liquid pressure is determined by ρgh, while the force F = pS is proportional to the area.
Model assumptionsLiquid at rest · g = 9.8 m/s² · gauge pressure shown, atmospheric pressure excluded · horizontal sensor · surface ripples are illustrative
