A vertical U-tube of uniform inner cross-section contains mercury in both of its arms. A glycerine (density 1.3 g cm³) column of length 10 cm is intro- duced into one of the arms. Oil of density 0.8 g cm is poured in the other arm until the upper surfaces of the oil and glycerine are in the same horizontal level. Find the length of the oil column. [IT] (Ans. 9.6 cm) 5.

A long U-tube contains mercury (density = 14 × 103 kg/m3). When 10 cm of water (density= 1.0 × 103 kg/m3) is poured into the left arm, the mercury in the right arm rises above itsoriginal level by:A. 0.36 cmB. 0.72 cmC. 14 cmD. 35 cmE. 70 cm

Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A1 of 10.9 cm2, and the right arm has a cross-sectional area A2 of 5.20 cm2. Two hundred grams of water are then poured into the right arm as shown in Figure b.Figure (a) shows a U-shaped tube filled with mercury. Both arms of the U-shaped tube are vertical. The left arm with cross-sectional area A1 is wider than the right arm with cross-sectional area A2. The height of the mercury is the same in both arms. Figure (b) shows the same U-shaped tube, but now most of the right arm is filled with water. The height of the column of water in the right arm is much greater than the height of the column of mercury in the left arm. The height of the mercury in the left arm is greater than the height of the mercury in the arms in Figure (a), and the difference in height is labeled h.(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? Your response differs from the correct answer by more than 100%. cm

A U-tube differential manometer connects two pipes A and B. The pipe A contains carbon tetrachloride having a specific gravity 1.2 under a pressure of 120 KPa. The pipe B contains oil of specific gravity of 0.65 under a pressure of 200 KPa. The pipe A lies 2.5 m above pipe B. Find the difference of pressure measured by mercury as fluid filling U-tube.

Consider a U-tube whose arms are open to the atmosphere. Water is poured into the U-tube from one arm, and light oil (ρoil 790 kg/m³) into the other. One arm contains 70 cm-high water, while the other arm contains both fluids with an oil-to-water height ratio of 6. Determine the height of oil in the right arm.a.hoil =73.2 cmb.hoil =85.3 cmc.hoil =64.4 cmd.hoil =96.1 cm
