To produce a discharge of 3.3 m3 /s, a Francis turbine will be operated at a speed of 60 rpm, r1 = 1.5 m, r2 = 1.20 m, B = 33 cm, β1 = 85°, and β2 = 165°. What should (a) α1 be for nonseparating fl ow to occur through the runner? What (b) power and (c) torque should result with this operation? Assume T = 10°C
