Calculate Pressure Applied on Fluid by Piston Cylinder Arrangement

[dE_logics]

In this attached image, a force is applied through a piston cylinder arrangement of cross section 1 cm...this force is uniformly distributed throughout the 1cm wide piston...so there's a certain pressure (x) that it poses on the fluid.

Will the fluid pressure under action of this force be = x?

Though it obviously should be, but I see some major advantages of this arrangement, that's why I'm asking.

It will, if it's a quasistatic process.

Will the fluid pressure under action of this force be = x?

At the top of the fluid, yes. At depths below the surface, you'll need to add a ρgh term due to the weight of the fluid.

It's not a process, it's a state.

At the top of the fluid, yes. At depths below the surface, you'll need to add a ρgh term due to the weight of the fluid.

Assume no gravity situation.

Verdict:Yes it's true.

 

[Dale]

Yes, this is essentially how hydraulics work.

 

[Doc Al]

Verdict:Yes it's true.

Yes, this is Pascal's principle.

Ok, thanks a lot everyone!
