Problem

A tank contains two immiscible fluids: an upper layer of oil

0.50\,\text{m}

thick (density

0.80\,\text{g\,cm}^{-3}

) floating on water (density

1.0\,\text{g\,cm}^{-3}

). A pressure gauge fixed at the bottom of the tank reads

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

above atmospheric pressure. Determine the depth of the water layer. (Take

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

.) a)

9.9\,\text{m}

10\,\text{m}

12.5\,\text{m}

10.4\,\text{m}
