why pressure increases with depth in fluid
Asked by sknv159357 | 05 Jan, 2023, 08:29: PM
As we go deeper into a fluid, there is more weight above us due to the fluid, which creates pressure. This means that the pressure increases with depth.
Mathematically, the pressure difference between two points in a fluid can be expressed as
P2 - P1 = hg
where,
P2 is the lower point of pressure, P1 is the higher point of pressure, h is the height or depth between the two points, and g is the acceleration due to gravity.
Now, if the lower point of pressure (P2) goes deeper, the height or depth (h) increases, which results in an increase in the pressure difference.
In other words, an increase in depth leads to an increase in pressure.
