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?

A bicycle tire pump has a piston with area 0.31 in2. If a person exerts a force of 18 lb on the piston while inflating a tire, what pressure does this produce on the air in the pump?
A large truck tire is inflated to a gauge pressure of 86 psi. The total area of one sidewall of the tire is 1,220 in2. What is the net outward force (in lb) on the sidewall because of the air pressure? (Enter the magnitude.)
A pitot tube (the figure) is used to determine the airspeed of an airplane. It consists of an
outer tube with a number of small holes B (four are shown) that allow air into the tube; that
tube is connected to one arm of a U-tube. The other arm of the U-tube is connected to hole A
at the front end of the device, which points in the direction the plane is headed. At A the air
becomes stagnant so that và = 0. At B, however, the speed of the air presumably equals the
airspeed B of the plane.
A pitot tube on a high-altitude aircraft measures a differential pressure of 240 Pa. What is
the aircraft's airspeed if the density of the air is 0.0330 kg/m³?
