QID 401075:
And yet, again, another water pressure equation plug-and-play. I'm going to get very good at these by all indications.

Give the equation for absolute pressure (pressure in a fluid):
{{c1::\(P = P_{0} + \rho gz\)}}
Extra
Absolute Pressure = (pressure at the surface of the fluid) + (pressure due to the fluid's weight at a specific depth)
P = Absolute pressure at a depth z
P₀ = Reference pressure (often atmospheric pressure if at the surface)
ρ = Density of the fluid
g = Acceleration due to gravity (≈ 9.81 m/s² on Earth)
z = Depth below the reference point
