Is the force that accelerates afluid betwen two points of different pressure conservative?
I added one more part above, about the force of gravity on an object in the fluid=be sure and see that. ## \\ ## Additional item: There is a vector identity, ## \int \nabla P \, d^3 x=\int P \, \hat{n} dA ##, (where ## \hat{n} ## is the outward pointing normal), and to have equilibrium, ## -\delta g \, \hat{z}+-\nabla P= 0 ##, (where ## \delta ## is the density (mass per unit volume)), so that you can actually derive Archimedes' principle from the pressure gradient force.Thank you so much for your answer
It is clear
