# Potential Flow Theory : Pressure Distribution, Bernoulli's Theorem and Flow Patterns

Consider the flow past a circular cylinder...

Plot the pressure coefficient Cp along the surface of the cylinder versus &#952; for O&#8804;&#952;&#8804; pi
i What is the value of Cp at &#952;=5O°
ii At what point around the cylinder's surface will the static pressure equal the freestream pressure.
iii If one combines a source and a sink of equal numerical strength (m) spaced 2b apart, with a uniform parallel flow in the x direction, sketch the resulting flow pattern.
If the source and the sink are moved infinitely close to one another, but the product mx2b is kept constant, sketch the resulting flow pattern.
