A “U†shaped tube (with a constant radius) is filled with waterand oil as shown. The water is a height h1 = 0.36 mabove the bottom of the tube on the left side of the tube and aheight h2 = 0.1 m above the bottom of the tube on theright side of the tube. The oil is a height h3 = 0.33 mabove the water. Around the tube the atmospheric pressure isPA = 101300 Pa. Water has a density of 103kg/m3.
A)What is the absolute pressure in the water at the bottom of thetube?
B)What is the absolute pressure in the water right at the oil-waterinterface?
C)What is the density of the oil?
D)Now the oil is replaced with a height h3 = 0.33 m ofglycerin which has a density of 1261 kg/m3. Assume theglycerin does not mix with the water and the total volume of wateris the same as before.
Now what is the absolute pressure in the water at the interfacebetween the water and glycerin?
E)How much higher is the top of the water in the tube compared tothe glycerin? (labeled d in the diagram)
F)What is the absolute pressure in the water at the very bottom ofthe tube?
