Two small vessels are connected to a U-tube manometercontaining mercury(relative density 13.56) and the connectingtubes are filled with alcohol (relative density 0.82). Thevessel at the higher pressure is 2 m lower in elevation than theother. What is the pressure difference between the vessels whenthe steady difference in level of themercury menisci is 225 mm?What is the difference of piezometric head? If an inverted U-tubemanometer containing a liquid of relative density 0.74 wereused instead, whatwould be the manometer reading for thesame pressure difference?
