Question: Consider the flow generated by a vortex of strength located at ( 1 , 1 ) , a source of strength q located at (

Consider the flow generated by a vortex of strength located at (1,1), a source of strength q
located at (0,1) in a free stream in the positive x-direction of velocity V
(i.e. like an airfoil flying
in a plume). Determine expressions for the force on the vortex and moment on the vortex,
calculated about the origin. Determine the proportion of the moment that is purely due to the
force acting on a lever arm
