The potential flow domain consist of three elementary flow models, they are namely.... (a) Uniform flow of angle of attack = 8 and free stream velocity U = 20 (b) (c) Doublet of strength = 15 and located at the point A (3.0; 2.0) m Sink of strength = 10 and located at the point B (1.0; 0.5) Determine: (1) (11) (111) (iv) m sec sec The potential function of flow field P(x, y) | The stream function of the flow field (x, y) The complex potential function F(z) The velocity component in x and y direction at the origin of coordinate system m sec
