Consider a potential flow with free stream velocity Vx over a spinning circular cylinder of radius R
and circulation Γ. The stream function, Ψ, where ψ=0 on the cylinder surface, in cylindrical
coordinates (r, θ) is given by
A
Vxr cos θ(1-R2r2)+ΓlnrR
B
Vxr cos θ(1+R2r2)+ΓlnrR
C
Vxr sin θ(1-R2r2)+ΓlnrR
D
Vαr sin θ(1+R2r2)+ΓlnrR

Correct : c
