Potential flow against a flat plate $($a$)$ can be described with the stream function Y $=$ Axy, where A is a constant. This type of flow is commonly called a "stagnation point flow since it can be used to describe the flow in the vicinity of the stagnation point at O$.$ By adding a source of strength m at O$,$ stagnation point flow against a flat plate with a bump$$ is obtained as illustrated in $($b$).$ Determine the relationship between the bump height, h$,$ the constant, A$,$ and the source strength, m$.$ If you need it sin$(20)=$sin$(7)$ cos$($a X Source $($a$)($b$)$
