Oil of relative density 0.75 floats on water in a tank. The depth of the water is 4 m and the depth of oil is 2.5 m.
a) How far below/above the oil surface is the imaginary water surface? (IWS same pressures but now all water)
b) What is the pressure at a point 2 m from the bottom of the tank?
a)
Distance from surface of the oil to the imaginary water surface (m)
b)
Pressure at point 2 m from the bottom of the tank (Pa)
