The Otawa power plant in Japan delivers 100 MW of power when the flow rate is 220 m^3/s and the effective head is 51 m. The diameter of the Kaplan turbine is D= 6.1 m, and the hub-to-tip ratio is k=D0.6. The generator has 48 poles and delivers power at a line frequency of 50 Hz. Find the efficiency of the turbine and calculate the flow angles entering and leaving the rotor. The relationship between the frequency, speed and poles is given by N=120*f/p
