6. generates electricity by converting the torque created by the rotation of the wind turbine. a. Drag type VAWT b. Lift type VAWT c. Drag type HAWT d. Lift type HAWT was proposed in the design of VAWT 7. To maximize the rotor efficiency, a. Symmetrical blade b. Composite gear box C. Magnetic levitation d. Impeller shaft 8. The of the turbine is defined by the ratio of the total swap area and the radius of the turbine. a. Efficiency b. Solidity c. Drag d. Nacelle 9. Few factors affect the power generation in HAWT. These factors include the _by the rotor blades of HAWT a. wind speed, power coefficient and the gear box b. wind speed, ear box and the area swept C. blade length, gear box and area swept d. wind speed, power coefficient and the area swept and known as 10. The theoretical maximum value of the power coefficient was found to be a. 0.593, known as the Betz limit b. 0.465, known as the Betz limit C. 0.251 known as Boltzmann constant d. 0.593 known as Bernoulli's constant
