# Find the distance along the curved surface from the leading edge from where the flow separates.

Consider an incompressible two-dimensional viscous flow over a curved surface .Let the pressure distribution on the surface be $$p(s)=2+sin\left ( \frac{\pi}{2}+s \right )\;N/m^2$$,where $$s$$ is the distance along the curved surface from the leading edge.Find the distance from where the flow separates.

$p\left ( s \right )=2+sin\left ( \frac{\pi}{2}+s \right )$
From the graph we easily see that at $$s = \pi$$ there will be adverse pressure gradient.So the separation will start from this point.
