A simple single-stage ie is being sign to produce powe lowing through a tube as in Fig. 4. We approximate both the stator and rotor as thin (bent sheet metal). The 16 stator (upstream) blades have ẞs1 = 0° and ẞst = 50.3°, where subscripts "sl" and “st” mean stator leading edge and stator trailing edge, respectively. At design conditions, the axial flow speed is 8.31 m/s, the rotor turns at 360 rpm, and it is desired that there be no swirl downstream of the turbine. At a radius of 0.324 m, calculate angles Bri and ẞrt (rotor leading and trailing edge angles), sketch what the rotor vanes should look like, and specify how many rotor vanes there should be.

Question
A simple single-stage axial turbine is being designed to produce power from water flowing through a tube as in Fig. 4. We approximate both the stator and rotor as thin (bent sheet metal). The 16 stator (upstream) blades have ẞs1 = 0° and ẞst = 50.3°, where subscripts "sl" and “st” mean stator leading edge and stator trailing edge, respectively. At design conditions, the axial flow speed is 8.31 m/s, the rotor turns at 360 rpm, and it is desired that there be no swirl downstream of the turbine. At a radius of 0.324 m, calculate angles Br and ẞt (rotor leading and trailing edge angles), sketch what the rotor vanes should look like, and specify how many rotor vanes there should be.
