Let fluid pressure be p at height z, and p + $\delta$p at z + $\delta$z. Let fluid pressure be p at height z, and p + $\delta$p at z + $\delta$z.
Force $F_z$, due to pressure $p$, acts upwards to support the fluid. Force $F_z$ acts upwards to support the fluid, countering pressure $p$.
Force $F_z + \delta F_z$, due to pressure $p + \delta p$, acts downwards due to weight of fluid Force $F_z + \delta F_z$acts downwards to counter pressure $p + \delta p$ and comes from the weight
above. of the liquid above.
