In the example in Figure 1, the manometer contains two fluids: water (density p 995 Kg/m³) and mercury (density pm Kg/m³). The density of blood is p 1,060 Kg/m³. Assume that there is atmospheric pressure at the interface between mercury and air. The interface between mercury and water is at z₁ = 7 cm, the interface between water and blood is at Z2 27 cm, and the tip of the manometer at za 10 cm.
