Choose 3 different standard flows. And the strength of these three flows will be 12, 17 and 47.
Derive expressions for the stream and potential functions of the combined flows and obtain expressions for velocity components and distributions over one stream line of your choice.
1- Use a graphical method to sketch the streamlines for the combined flow, showing the position of any stagnation points.
2- Also, assuming you can change the position of the flows relative to each other, how will this affect the resulting stream lines? Try only one change.
3- Obtain and comment on the pressure distribution in the flow field at any stream line of your choice.
