The mean radius of an axial flow reaction turbine is 2.6 ft. and the axial velocityis 25 ft./s. The wicket gates are turned at an angle such that relative velocity at theinlet flow makes an angle of -45° with the blade velocity. The wheel and hub radiiare 3.6 ft. and 1.6 ft., respectively. The turbine rotates at 240 rpm. If water leaves theblade in a purely axial direction, calculate H and all relevant angles.Ans: H=81.87 ft.; α1=31.8°; β2=20.93°
