A sketch of the arithmetic mean radius blade sections of an axial-flow water turbine stage is shown in Fig. P12.51. The rotor speed is 1500 rpm.

(a) Sketch and label velocity triangles for the flow entering and leaving the rotor row. Use V for absolute velocity, W for relative velocity, and U for blade velocity. Assume flow enters and leaves each blade row at the blade angles shown.

(b) Calculate the work per unit mass delivered at the shaft.
