I think the oil is above the water. What is bothering me is, if the water force is equal to dF=ρwghwdh from 1.2 to 2 or should i also add the force that the oil apllies to the water and use df=ρwghwdh(this integral from 1.2 to 2) + ρoghwl to add the pressure the oil adds?
ρw=density of water...
1. A tank with vertical walls, 2m wide and 2m long and 2.5m high, is filled with 4800 litres of water (density 1000 kg/m3) and 3200 litres of light oil (density 900 kg/m3). Calculate the magnitude and location of the resultant force on each of the vertical walls of the tank.
2. By doing some...
