Upon receiving the data, the equation of the two-dimensional velocity field is as follows: V-(u.v) (0.6+0.9x)i + (1.6-0.9y)j where x- an y- coordinates are in m, time in s, and the magnitude of the velocity is in m/s. Determine, based on the equation: (a) A stagnation point, if existed in the tornado. (b) Sketch the velocity vector for +/-4 m from the stagnation points. (c) Sketch the relevant streamlines on a different graph. (d) Determine the material acceleration of the velocity field of the tornado. (e) Determine the rate of translation for the velocity field of the tornado. (f) Determine the rate of shear strain for the velocity field of the tornado. (g) Verify if the flow is a compressible or incompressible flow. (h) Verify if the flow is rotational or irrotational flow.
