ALL WORK. Problem 1. A. For a certain incompressible flow field the velocity vector is given as = (2x-2)+ (-2y+2). Determine the location of any stagnation points in the flow field. (8 pts) 40 pts B. Consider the velocity field in Part A, and determine the equations of streamlines and streaklines for the flow that passes through the stagnation point in part A. (9 pts) C. Consider the velocity field in Part A and derive a general expression for the acceleration and determine the value of the total, x component, and y-component of acceleration at (x, y) = (2,3)? (13 pts) = i+ f. Determine the equation of the 1+t y 1+2t D. An incompressible flow field is given by V pathlines that pass through the stagnation point (xo, yo) at time t = 0. (10 pts)
