It is the fluid pressure equation. P stands for the pressure, ρ stands for the density of the fluid medium, g is the acceleration due to gravity (9.81ms^-2 on Earth) and h is the height of the measured pressure's distance from the surface of the fluid itself.
HKCEE physics paper: Peter filled a tube measuring 3m tall with water to the brim. Find the pressure at the middle of the water tube. (Density of water at r.t.p= 997kgm^-3)
By P=ρgh
P=(997)(9.81)(1.5)
P=14700 Pa (3 sig fig)
