Chapter 1.11, Problem 74P
Consider a U-tube whose arms are open to the atmosphere. Now water is poured into the U-tube from one arm, and light oil (ρ = 790 kg/m3) from the other. One arm contains 70-cm-high water, while the other arm contains both fluids with an oil-to-water height ratio of 4. Determine the height of each fluid in that arm.

Consider a U-tube filled with mercury. The diameter of the right arm of the U-tube is D = 1.5 cm, and the diameter of the left arm is twice that. Heavy oil with a specific gravity of 2.72 is poured into the left arm, forcing some mercury from the left arm into the right one. Determine the maximum amount of oil that can be added into the left arm.
Milk with a density of 970 kg/m^3 is transported on a level road in a 9-m long, 3-m diameter cylindrical
tanker. The tanker is completely filled with milk, i.e., no air space in the tank. If the truck is accelerating
from a stop signal at 7.0 m/s^2 to the left, determine the pressure difference between the maximum
and minimum pressures in the tank. Depict on the figure the location of the minimum and maximum
