text: They are similar to Francis turbines, but have adjustable propeller blades, allowing maximum efficiency over a range of heads.
text: If the angular velocity of the runner could be such that v = u, the water would drop directly down, and the efficiency of the turbine would be a maximum.
text: It is also found that efficiency of torque converter is maximum at very low speeds.
text: As discussed earlier, a wind turbine would ideally operate at its maximum efficiency for below rated power.
text: In this method, a wind turbine operates at maximum efficiency under low and medium speed and at high wind speed, the wind turbine is controlled by the stalled blade by limiting the rotational speed.
text: As discussed earlier, a wind turbine would ideally operate at its maximum efficiency for below rated power.
