A windmill produces mechanical power according to this formula: P=VmgV3A, where n is its efficiency (assume n=60.%), g=density of air (1.00kg/m³), V=wind speed in m/s (assume 5.0 m/s), and A is the cross section of the mill that faces the wind (assume it is circular with a radius of 35.0m). a. How many kW does the windmill produce? b. To load level, we have a battery storage device that can store 2.00 MWh. How long will we be charging it? C. If the energy storage density we can achieve is 125 Wh/kg, how big is this storage battery in tonnes?

Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
