Question #169240

A vertical storage tank has 2.5 m of heavy fuel oil (p=0.94g cm3) Floating on 0.5 m of water (p=1.0 g cm3). What is the pressure at the bottom of the tank due to the liquid in it?

Expert's answer

$p=p_1+p_2=\rho_1gh_1+\rho_2gh_2=$

$=940\cdot9.8\cdot2.5+1000\cdot9.8\cdot0.5=27930\ (Pa)$ .Answer
