Fluids course work

    1. The problem statement, all variables and given/known data

    A sphere of radius a is surrounded by a fluid, flowing with a uniform velocity U far from the sphere. Imagine the sphere divided into two hemispheres by a plane perpendicular to the direction of flow. Calculate the force on each hemisphere, assuming the pressure far from sphere is P. Hence show that the effect of the flow is to decrease the force on each hemisphere.

    Assume fluid is both inviscid, of constant density and irrotational.


    I am not sure how to start this problem at all. Would I use mapping of images or how would I start this off....
