If so, where is it? Question #7 A steady, incompressible, two-dimensional velocity field is given by the following components in the xy- plane: u = 1.1 + 2.8x + 0.65y v = 0.98 2.1x - 2.8y Calculate the acceleration field (find expressions for acceleration components ax and ay), and calculate the acceleration at the point (x, y) = (2, 3). Question #8 u = Uentrance + (Uexit Uentrance) x2 L² For the velocity field of figure below, i. Calculate the fluid acceleration along the diffuser centerline as a function of x and the given parameters. Dentrance ii. For L=2.0 m, entrance = 30.0 m/s, and exit = 5.0 m/s, Calculate the acceleration at x = 0 and x = 1.0 m. 0 u(x) Uentrance x=L Dexit 0 ENG × ^ 5:24 PM 10/31/2016
