Chapter 2: Problem 5
Two small vessels are connected to a U-tube manometer containing mercury (relative density 13.56) and the connecting tubes are filled with alcohol (relative density \(0.82\) ). The vessel at the higher pressure is \(2 \mathrm{~m}\) lower in elevation than the other. What is the pressure difference between the vessels when the steady difference in level of the mercury menisci is \(225 \mathrm{~mm}\) ? What is the difference of piezometric head? If an inverted U-tube manometer containing a liquid of relative density \(0.74\) were used instead, what would be the manometer reading for the same pressure difference?
