And not on the amount/weight of the water in let’s say a conical container?
In: Physics
Pressure is Force × Area.
Assuming I keep the **area** over which I measure the Pressure as a **constant**, Pressure will only depend on the Force.
Now, the question arises, what Force? The force we are talking about is the Force of Gravity. We know that Gravity only occurs in one direction, downwards.
Therefore, only water molecules **directly above** the area we want to measure needs to be counted.
To count the **mass** of the water above the area, all we need to do is multiply the density of water with the volume of water.
Volume is Height × Bottom Area
As the area of the measured surface is constant, volume only depends on the height.
TL;DR ::: Assuming area being measured is constant, only the mass above that area exerts its weight and is counted for pressure.
