# Pressure in Tank with Two Liquids

APPH12-FEIOSF

What is the pressure $50.0$ $cm$ from the bottom of a $5.00$ $m^3$ tank if it is filled with $3.50$ $m^3$ of a liquid with a specific gravity of $1.23$ and $1.00$ $m^3$ of a second liquid with a specific gravity of $0.900$? The bottom of the tank has a surface area of $1.00$ $m^2$. Use $1.01\times10^5\ Pa$ for atmospheric pressure and $9.8\ m/s^2$ for $g$. Assume the liquids have settled into two separate layers. The diagram below is not drawn to scale.

A

$1.48\times10^5\text{ }Pa$

B

$1.07\times10^5\text{ }Pa$

C

$1.52\times10^5\text{ }Pa$

D

None of the above.
