Chapter 4, Problem 4RQ
  1. 4. Which of the following sentences is the best example of good technical writing?
    1. A.    A water hammer happens when a surge in pressure reaches the end of a pipe; since water is incompressible below the saturated liquid/vapor line, the momentum is stopped over a short distance and the resulting forces are large.
    2. B.     A surge in water pressure can cause a large force. This force, called a water hammer, will cause the pipes to fail, if left unchecked.
    3. C.     A water hammer can easily break steel pipes.
    4. D.    A surge in water pressure can cause a large force. This force, called a water hammer, can result in amazing failures. It is one of my favorite modes of failure.

Recall the discussion on spacecraft from the chapter opener. The following problems consider a rocket launch from Earth’s surface. The force of gravity on the rocket is given by F(d)=−mk/d2, where m is the mass of the rocket, d is the distance of the rocket from the center of Earth, and k is a constant. 172.  As the rocket travels away from Earth’s surface, there is a distance D where the rocket sheds some of its mass, since it no longer needs the excess fuel storage. We can write this function as F(d)=⎨(−m↓1 k / d^2) if d < D                                                                                  (−m↓2 k / d^2) if d ≥ D Is there a D value such that this function is continuous, assuming m1≠m2?
When two fluids differ in densities, which of the following will always occur?A. The denser fluid will always stay at the bottom of the container.B. The denser fluid is heavier in mass if the volume of the liquids is equal.C. The lighter fluid experiences more vapor pressure than the denser fluid.D. The lighter fluid has more tendency to exhibit capillary movement.
