the top with oil of density 0 85 g/cm3 The pressure at
the bottom of the bottom of the tank, due to these liquids is
a)1 85 dyne/cm2 b)89 25 dyne/cm2 c)462 5
dyne/cm2 d)500 dyne/cm2

Hello,
Pressure at the bottom of the tank(P)
= pressure by water level + pressure by the oil
= h 1 d1 g + h2 d2
g
Given that
h1 = h2 = 2 5m = 250 cm
d1 = 1 g/cm3
d 2 = 0 85 g/cm3
g = 981 m/s2
P = 981(1*250 + 0 85*250)
=> P = 981*250*1 85
=> P = 453712 5 dyn/cm2
