Fig. 321. — Multiple-step Velocity Diagram. with the triangles in sequence, and showing how the bucket profilesare fitted to the lines of velocity direction. For the discussion of workrelations, the single-pole diagram in Fig. 322 is preferable. Here therelative velocities of entrance and of exit… … Fig. 322. — Velocity Diagram for a Three-impulse Stage. and dropping.for the time the factor W/g in Eq. (214), we have thefollowing expressions for the driving forces in the respective stages: Fi = 2iU - T);F2 =2{U -ZT)]F, = 2(U -5T). (236) Of course, the velocity factor T in P^ = F^T is the same…
