Water flowing at V_a
= 6 m/s is directed from the stator onto the blades of an axial flow turbine at an angle of

₁
= 30°. If the turbine blades are rotating at 60 rad/s, determine the required angle b1 of the blades so that they properly accept the flow. What should be the angle

₂
of the stator so that water is delivered to it from the turbine at an angle of

₂
= 15°? The turbine has a mean radius of 500 mm.
