Multifluid manometer

  1. Feb 4, 2009 #1

    I came up to some problems involving multifluid manometers, which generally are U-tubes or double U-tubes with stacked immiscible fluids.
    I wonder what is the reason to use such systems? Are they just a product of teachers to artificially complicate problems? Couldn't find anything what could explain practical reasons of such devices.

    The U shaped manometer is a cheap and effective way of measuring pressure.If you pour two immiscible liquids of different densities into a manometer then you can easily compare the densities by measuring the heights above the interface of the two liquid columns
