The stream function for a two dimensional, incompressible flow field is given by the equation

where the stream function has the units of with x and y in feet. (a) Sketch the streamlines for this flow field. Indicate the direction of flow along the streamlines. (b) Is this an irrotational flow field? (c) Determine the acceleration of a fluid particle at the point x = 1 ft, y = 2 ft.
