Textbook Question
Chapter 2, Problem 2.7P
The velocity field given in Problem 2.3 is called source flow, which will be discussed in Chapter 3. For source flow, calculate:
a. The time rate of change of the volume of a fluid element per unit volume.
b. The vorticity.
Hint: It is simpler to convert the velocity components to polar coordinates and deal with a polar coordinate system.
