The tank has a square$-$shaped base $2m2m$ and is filled with oil $($density $=850k\frac{g}{m^3})$ and Patm $=$

$101$kPa. The pipe and manometer section at B are filled with water up to the interface with the oil.

Compute:

$($A$)$ Absolute pressure $(Pa)$ at the bottom of the tank

$($B$)$ Hydrostatic force $(N)$ on the bottom of the tank $-$ see problem statement for tank

dimensions.

$($C$)$ Gauge pressure $(Pa)$ at the interface of the water$-$oil in the manometer section

$($D$)$ Gauge pressure $(Pa)$ at point $B$

$($E$)$ Pressure head, $h(m$ of water$),$ at point $B$
