Hi Tmoose,
I have referred that particular documents and many other documents available on web. Anywhere they are not saying about the manually determining. the radial and axial loads. Infact they says ,it is tricky to determine the exact area which comes in effect for calculating the forces.and suggesting rotodynamic analysis. But I cannot do that . So I would need help in identifying atleast approximate way in determining the area to be considered. Appreciate your reply.
