The stream function for a given 2-D horizontal flow field is 3 2 ψ = 4x −12xy , where the stream function has a unit of cubic meter per minute, while x and y in meters.

a) Determine the flow velocity at two points in the flow field, A at (2, 0) and B at (0, 2).

b) Estimate the rate of flow across the straight line between A and B.

c) Show evidence that the flow is irrotational.
