1. The problem statement, all variables and given/known data The two-dimensional steady flow of a fluid with density ρ is given by v=K(-yex + xey) / (x2 + y2) where K is a constant (a) Can this flow corespond to the flow of anincompressible fluid? (b) Determine and sketch the streamlines of this flow. (c) Determine and sketch the aceleration of this field (d) Determine the pressure difference between two points that are a distance r1 and r2 away from the origin. (r2 > r1) ? 2. Relevant equations dx/u=dy/w 3. The attempt at a solution I see that there is x^2+y^2, this makes me think that there is a circle based streamline flow?? I do not understand how I can visualize this in my head, such an equation. How can I know whether its incompresssible? The acceleration should be the derivative of those streamlines I guess.. Can anybody help me out with these questions PLEASE?
