Question
Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A1 of 9.3 cm2, and the right arm has a cross-sectional area A2 of 5.80 cm2. Two hundred grams of water arethen poured into the right arm as shown in Figure b.
(a) Determine the length of the water column in the right arm of the U-tube. cm
(b) Given that the density of mercury is 13.6 g/cm3, what distance h does the mercury rise in the left arm? cm
Explanation / Answer
a)Density = Mass/volume = 1000 kg/m^3 =>Volume = (200/1000)/1000 = 0.0002 m^3 = 200 cm^3 Length of water column = Volume/Area = (200/5.8) = 34.48275862 cm
