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 $F_z$ acts upwards to support the fluid, countering pressure $p$.

\end{align*}
The equation applies for any fluid.
The -ve sign indicates that as z, height, increases, p, pressure, decreases.
The -ve sign indicates that as $z$, height, increases, $p$, pressure, decreases.
