Assessment activity $1\mathrm{.}3$

$($Individual$)$

A heavy tank is shown in Figure $1\mathrm{.}8.$ It contains oil to a depth of $600mm$ and water to a depth of $1m.$ If the tank is pressurised to $800$kPa, what will be the downward movement of the oil and water? The bulk moduli of the water and oil are $2070$MPa and $2040$MPa respectively. Ignore the hydrostatic pressure resulting from the liquids. The tank has an internal diameter of $500mm.$
