The indicating liquid in the manometer shown in the figure below is water and benzene with a density of 880 kg/m3. These two liquids are essentially insoluble in each other. If the two liquids are essentially insoluble in each other. If the manometer reading is AZ = 43.99 cm of water, what is the pressure difference P1 - P2 in kN/m2.
In terms of benzene, ρ = sp gr x density of water
P a (880 kg/m3 )(0.06 m) (0.4963 m)= p a
We therefore solve for 7343 N/m ,
γ benzene + − = ≈ 7343/9.81 .
P1 - P2 = ≈ 3 748 kN/m 2
