What does it mean for there to be uniform pressure?

SUMMARY

The discussion centers on the concept of uniform pressure within a closed hemispherical shell filled with fluid, specifically addressing the implications of the term "uniform pressure p." Participants clarify that uniform pressure indicates that the pressure is constant at all points within the fluid, regardless of height. This simplification allows for easier calculations, as it negates the need to account for variations in pressure due to gravity or fluid dynamics. The discussion emphasizes that the problem assumes a stationary fluid, potentially in a zero-gravity environment, where pressure remains consistent across the shell's surface.

Homework Statement



A closed hemispherical shell of radius R is filled with fluid at uniform pressure p. The net force of the fluid on the curved portion of the shell is given by:

I'm not even posting the answers because I'm not looking to get an answer.

I don't understand what it means for the fluid to be "at uniform pressure p".

At any height beneath the surface of this hemispherical shell, shouldn't the pressure be the sum of the weight of the water above it plus atmospheric pressure?

What does the uniform pressure, ## p ## mean?

I would guess that the object is in space with no significant gravity and the fluid is stationary so there are no dynamic fluid forces.
Just assume the pressure is the same at all points in the fluid.

I would assume the same

weight of the water
It does not specify water. A fluid can be a gas, so the variation in pressure may be negligible.
 
It is likely to make the problem a lot easier :-)
 
It most likely means that fluid pressure is not variable across the shell, at all points of the shells surface the pressure is not polarized to anyone particular sector of it .

It is probably to make the question easier
