A sketch of the arithmetic mean radius blade sections ofan axial-flow water turbine
Chapter 12, Problem 12.47(choose chapter or problem)
A sketch of the arithmetic mean radius blade sections ofan axial-flow water turbine stage is shown in Fig. P12.48. Therotor speed is 1500 rpm. (a) Sketch and label velocity trianglesfor the flow entering and leaving the rotor row. Use V for absolutevelocity, W for relative velocity, and U for blade velocity.Assume flow enters and leaves each blade row at the bladeangles shown. (b) Calculate the work per unit mass deliveredat the shaft
