Question

The wind velocity at three places A,B,C are 5km/hr,15km/hr,10km/hr respectively.Which is the most suitable place for installing wind mill and why?​

Answer 1

The most suitable place for installing wind mill will be B 15 km/hr.

• A windmill converts wind energy into electrical energy.
• A windmill has large blades that are rotated due to the wind and these blades are connected to generators that give electricity as output.
• The kinetic energy of blades is converted to electrical energy.
• Now, higher speed of wind would make the blades rotate at higher speed thus giving higher kinetic energy.
• Hence, generation of electricity would be higher.
• Hence, it is preferable to set up a wind mill at a location where speed of the wind is highest.
• Out of the three locations, speed of wind is highest at location B i.e 15 km/hr.
• Thus, location B is most suitable.

Answer 2

Answer:

B, Maximum velocity required is 15km/h. At lower speed it will not work. At very high speed it may break the blades.
