Question: 1. A long right circular cylinder of radius a m is held with its axis normal to an irrotational inviscid stream of U. Obtain an expression for the drag force acting on a unit length of the cylinder due to pressures exerted on the front half only.
2. A two-dimensional fluid motion is represented by a point vortex of strength 0 set at unit distance from an infinite straight boundary. Draw the streamlines and plot the velocity distribution on the boundary when Γ = π. (U of L)
