Question

4.16 A fluid flows along the x axis with a velocity given by
= (x/t)î, where x is in feet and t in seconds. (a) Plot the speed
for 0 ≤ x ≤ 10 ft and t = 3 s. (b) Plot the speed for x = 7 ft
and 2 ≤ t ≤ 4 s. (c) Determine the local and convective accel-
eration. (d) Show that the acceleration of any fluid particle in
the flow is zero. (e) Explain physically how the velocity of a
particle in this unsteady flow remains constant throughout its
motion.

Fluid Mechanics

The study of how gases and liquids behave, particularly the forces they generate, is known as fluid mechanics. Fluid dynamics is a topic that interests many scientific fields. For instance, in order to anticipate the weather, meteorologists attempt to predict the velocity of the planet's fluid atmosphere.
