A simple single-stage axial turbine is being designed to produce power from water flowing through the tube. The stator blades have β_sl=0,β_st=50.3. At design condition the axial flow speed is 8.31 m/s, the rotor turns at 360rpm, and it is desired that there be no swirl downstream of the turbine. At a radius of 0.324 m, calculate angles β_rl,β_rt (rotor leading and rotor trailing edge angles).
