Problem

A tank contains a

40\,\text{cm}

layer of oil of density

800\,\text{kg m}^{-3}

floating on

1.2\,\text{m}

of water of density

1000\,\text{kg m}^{-3}

. Calculate the absolute pressure at the bottom of the tank. Atmospheric pressure is

1.01\times10^{5}\,\text{Pa}

and

g = 9.8\,\text{m s}^{-2}

. (a)

1.32\times10^{5}\,\text{Pa}

(b)

1.04\times10^{5}\,\text{Pa}

(c)

1.16\times10^{5}\,\text{Pa}

(d)

1.14\times10^{5}\,\text{Pa}
