Determine the pressure difference between water lines A and B as indicated by the manometer shown in the figure. You may take the density of mercury to be ? _Hg = 13,600 kg/m ³ .

Suppose that we want to use a different manometer, one that has a manometer fluid with a density of ? _m = 2500 kg/m ³ (2.5 times the density of water). What would the height of the manometer fluid be for the same pressure difference between the two tanks? (It is 12.2 cm for the mercury manometer.) Is this practical?

B Water- U 12.2 cm Mercury.
