Problem 5.76 [Difficulty: 3] Given: Stream function Find: If the flow is incompressible and irrotational Solution: Basic equations: Incompressibility x u y v 0 Irrotationality x v y u 0 Note: The fact that ψ exists means the flow is incompressible, but we check anyway ψ xy ()3 x 5 y 10 x 3 y 3 3x y 5 Hence uxy () y ψ 5 30 x 3 y 2 15 x y 4 vxy x ψ 30 x 2 y 3 15 x 4 y 3y 5 For incompressibility x 15 x 4 90 x 2
