In the conical nozzle shown in Fig. P4.7R the streamlines are essentially radial lines emanating from point A and the fluid velocity is given approximately by V = C/r² where C is a constant. The fluid velocity is 2 m/s along the centerline at the beginning of the nozzle (x = 0). Determine the acceleration along the nozzle centerline as a function of x. What is the value of the acceleration at and x = 0 x = 0.3 m?
