Sketched in Fig. P12.10 are the upstream [section (1)] and downstream [section (2)] velocity triangles at the arithmetic mean radius for flow through an axial-flow turbomachine rotor. The axial component of velocity is 50 ft/s at sections (1) and (2).

(a) Label each velocity vector appropriately. Use V for absolute velocity, W for relative velocity, and U for blade velocity.

(b) Are you dealing with a turbine or a fan?

(d) Sketch a reasonable blade section. Do you think that the actual blade exit angle will need to be less or greater than 15°? Why?
