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 ΔZ = 37.19 cm of water, what is the pressure difference P1 - P2 in kN/m2. Show detailed calculations.
guage pressure = "\\rho \u00d7 g \u00d7 h" ="37.19\/100 \u00d7 9.8 \u00d7 880" = 3207.27 Pa
"\\therefore" P2 - P1 = 3207.3 Pa
