As a valve is opened, water flows through the diffuser shown in Fig. P4.17 at an increaseing flowrate so that the velocity along the centerline is given by where c, and are constants. Determine the acceleration as a function of x and t. If V0 = 10 ft/s and l = 5 ft what value of c (other than is needed to make the acceleration zero for any x at Explain how the acceleration can be zero if the flowrate is increasing with time.
