ssume that the two liquids in the U-shape tube are water and oil. If the water stands 18 cm above the interface and oil stands 24 cm above the interface, then the density of oil is _

A U-tube contains water and oil. The oil of density 800kg / (m ^ 3) rest on the surface of the water in the right-hand leg to a depth of 5cm. if the level of water in the left hand leg is 10cm above the level of water in the right hand leg, determine the pressure difference between the two legs. The density of water is 1000kg / (m ^ 3)

A U-tube open at both ends is partially filled with water (Figure (a)). Oil (𝜌 = 750 kg/m3) is then poured into the right arm and forms a column L = 6.96 cm high (Figure (b)).Three figures portray a U-shaped tube with vertical arms on the left and right of equal height.In figure a, the liquid inside the tube is labeled water, and the columns of liquid in each arm are the same height. The pressure outside the tube is labeled P0.In figure b, an additional liquid labeled oil has been added to the right arm. The column of oil sits atop the column of water in the right arm, and the upper surface of the oil is at a greater height than the surface of water in the left arm. The difference in height is labeled h. The height from the bottom of the column of oil to the top of this column is labeled L.Figure c depicts the same situation as figure b, except that air blowing over the top of the left arm affects the heights of the surfaces of liquids in each arm. The velocity of air over the top of the left arm is labeled vector v. A shield covers the top of the right arm. The height of the top of the column of water in the left arm is equal to the height of the top of the column of oil in the right arm. The height from the bottom of the column of oil to the top of this column is labeled L.(a) Determine the difference h in the heights of the two liquid surfaces. (The density of water is 1.00 ✕ 103 kg/m3.) Your response differs from the correct answer by more than 100%. cm(b) The right arm is then shielded from any air motion while air is blown across the top of the left arm until the surfaces of the two liquids are at the same height (Figure (c)). Determine the speed of the air being blown across the left arm. Assume the density of air is 1.29 kg/m3. Your response differs from the correct answer by more than 10%. Double check your calculations. m/s

17. A uniform U-tube is partially filled with water. Oil, of density 0.75 g/cm3, is poured into theright arm until the water level in the left arm rises 3 cm. The length of the oil column is then:A. 2.25 cmB. 8 cmC. 6 cmD. 4 cmE. need to know the cross-sectional area of the 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

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.
