Two vertical cylindrical storage tanks, Tank A and Tank B, are situated on flat ground.
Tank A has a base of cross-sectional area S S\,S and is filled to a depth of H H\,H with an organic solvent of density 800 kg/m3.
Tank B has a base of cross-sectional area 2.5S 2.5S\,2.5S and is filled to a depth of 0.6H 0.6H\,0.6H with a salt solution of density 1200 kg/m3.
Compare the hydrostatic pressures exerted by the liquids at the bottom of each tank, explaining the effect of the different base areas on these pressures.
