Pressure_and_buoyancy Liquid

in gravitational field, liquids exert pressure on sides of container on within liquid itself. pressure transmitted in directions , increases depth. if liquid @ rest in uniform gravitational field, pressure, p, @ depth, z, given by

p
=
ρ
g
z



{\displaystyle p=\rho gz\,}

where:

ρ



{\displaystyle \rho \,}

density of liquid (assumed constant)




g



{\displaystyle g\,}

gravitational acceleration.

note formula assumes pressure @ free surface zero, , surface tension effects may neglected.

objects immersed in liquids subject phenomenon of buoyancy. (buoyancy observed in other fluids, strong in liquids due high density.)
