Question
Determine the pressure at bottom of an open tank if it contains layers 10 cm of oil, 30 cm of water and 5cm of mercury.
Given that the densities of oil, water, and mercury are 850 kg/m^3, 1000kg/m^3 and 13600kg/m^3 respectively.

figure the weight of each of the substances for a column 1m^2 in area.
weight=density*area*9.8N/kg*heightinMeters
Now add the weights.
Divide by 1m^2, that is the pressure in Pascals.
weight=density*area*9.8N/kg*heightinMeters
Now add the weights.
Divide by 1m^2, that is the pressure in Pascals.
