GEOLOGY

Detailed explanation-1: -When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin.

Detailed explanation-2: -Again, there are two types, both centrifugal and axial, but axial turbines are far more common. Considerations in the design of the blades is different, however. Because the turbine is removing pressure instead of adding it, there is a favorable pressure gradient.

Detailed explanation-3: -Impulse-Reaction Turbine: In an impulse reaction turbine, steam expands both in fixed and moving blades continuously as the steam passes over them.

Detailed explanation-4: -The wind turbine generally consists of two types of shafts i.e. main shaft and generator shaft. The main shaft is a low speed shaft with the turbine rotor bolted through a strong disc. The generator shaft is a high speed shaft coupled with the output shaft of the gearbox.
