A trace from the schlieren photograph of the flow around a corner reveals the edges of the expansion fan as shown below. The leading and trailing edges of the expansion fan make the angles as shown. Assuming γ=1.4 the angle of the expansion fan (in degrees) is _______ (in two decimal places)
Prandtl Meyer function is given by
ν(M)=√(γ+1/γ-1)tan-1√((γ-1)/(γ+1)(M2-1))-tan-1√(M2-1)
Prandtl Meyer function is given by
ν(M)=√(γ+1/γ-1)tan-1√((γ-1)/(γ+1)(M2-1))-tan-1√(M2-1)
