Let p be the pressure in Pascals,

g – acceleration of gravity,

m – mass,

ρ is the density.

The pressure of kerosene is equal to its weight divided by the area: p = mg: S, since m = ρ * V, then

p = (ρ * V * g): S, V = Sh.

Hence p = (ρ * S * h * g): S = ρ * h * g

and

h = p: (ρ * g)

h = 1600: (800 * 9.81) = 19.62 m
