Afluid flows along the x axis with a velocity given by v = ( x / t ) ˆ i , 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 acceleration. (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.
