Unformatted text preview: irrotational and derive an expression for the velocity potential. 3. The stream function of a flow field is 3 2 By y Ax − = ψ , where 1 1 2 − − ⋅ ⋅ = s m A , 1 1 3 2 − − ⋅ = s m B and the coordinates are measured in meters. Find an expression for the velocity potential. 4. Consider the flow field represented by the velocity potential 2 2 By Bx Ax − + = φ , where A = 2 m s1 , B = 2 s1 , and the coordinates are measured in meters. Obtain expressions for the velocity field and stream function. Calculate the pressure difference between the origin and point (x,y) = (1,2)....
