Textbook Question

Chapter 12.1, Problem 4cT

A syringe is used to remove some water from the left side of the U-tube. The water level on the left side is seen to be lowered, butthe water level on the right does not change.

Consider the following student dialogue:

Student 1: | “The pressure at point F must now be higher than atmospheric pressure because the water there is being pushed up against the stopper.” |

Student 2: | “I think that the pressure at point E must be the same as at point A because they are at the same level. These points are both at atmospheric pressure. So the pressure at point F is lower than atmospheric pressure because know that pressure gets less as you go up.” |

Student 3: | “But water is more dense than air so the pressure at F cannot be less than atmospheric pressure.” |

With which student(s), if any, do you agree?

4. The maximum depth, dmax that a diver can snorkel is set by the density of the water and the fact that human lungs can function against a maximum pressure difference (between inside and outside the chest cavity) of 0.050 atm. What is the difference in dmax for fresh water and the water of the Dead Sea (the saltiest natural water in the world, with the density of 1.5 x 10^3 kg/m3)?

Looking at the figure below, a small parallelepiped of fluid centered on the point, explain why the pressure will be independent of x and z? And what will you need to know to determine the pressure in y?
