4.16 A fluid flows along the x axis with a velocity given by V = = = (x/t), 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.

explain part d
Expert Solution
Step 1
Given data:-
The given velocity function,
V=(X/t)i+0j+0k
we know,
i is a function of u so, u=(X/t)
j is a function of v so, v=0
k is a function of w, then w=0
