- A steady, incompressible, two-dimensional velocity field is given by V= (u, v) = (0.5 +0.8x)+ (1.5-0.8). where the x-and y-coordinates are in meters and the velocity is in m/s. (a) Determine if there are any stagnation points, if so, where? (b) Calculate the material acceleration at the point (x = 1.25 m, y=2.75 m) 2- Calculate the various kinematic properties of the velocity field given in the previous problem, namely, the rate of translation, rate of rotation, linear strain rate, volumetric strain rate and the streamline equation. Verify that this flow is incompressible.
