Question

When fan rotates how do we get to feel the air? is it because the fan exerts pressure on the layer of air present in contact with its wing or ???????????????????????

Answer 1

Yes, you are right but for further explanation please refer this: 1.Direction of air coming from fan depends upon directional arrangements of leafs. If u wil change the direction of leaf u wil get air in backwards........----- 2.The slicing of the air caused by the fan blades is what pushes the air downward, causing the breeze created by the ceiling fan. This whole process circulates the air through the room, as air moves in to replace the air that has been pushed down from the ceiling.
