1) A velocity field is given by V = ax?i-bxyl, where a = 2 m-'s-1 and b = 4 m-'s-1. (5 points) is the flow field one, two, or three-dimensional? Why? Is it steady? Why? (15 points) Find the equation of the streamline passing through the point (x,y) = (2,1).
6.35 The x component of velocity in a two-dimensional incompressible flow field is given by uAx; the coordi nates are measured in meters and A 3.28 m There is no velocity component or variation in the z direction. Calculate the acceleration of a fluid particle at poin (x, y)- (0.3, 0.6). Estimate the radius of curvature of the streamline passing through this point.

6. Assume that ( U U ), ( V V ) and (W, w) are three normed vector spaces over R. Show that if A: U V and B: V W are bounded, linear operators, then C = BoA is a bounded, linear operator. Show that C| < |A|B| and find an example where we have strict inequality (it is possible to find simple, finite dimensional examples).
