Hot air can make fan blades turn by creating a pressure difference between the front and back of the blades. When air is heated, it expands and becomes less dense, creating a lower pressure behind the blades. The higher pressure in front of the blades then pushes the blades in the direction of the lower pressure, causing them to turn.

What force is applied in working of a fan?

In a fan, the force that is applied is typically generated by an electric motor that drives the rotation of the fan blades. This motor creates a torque that spins the blades and moves air through the fan. The movement of air is then produced by the fan blades as they push or pull the air in the desired direction.


How do the blades of a ceiling fan turn for warm air?

Ceiling fan blades are set to rotate in a counterclockwise direction to create a breeze that circulates cool air and creates a wind-chill effect. This can help make a room feel cooler in warm weather. To promote warm air circulation in colder weather, the blades can be set to rotate in a clockwise direction to gently draw air upward and redistribute warm air that has risen to the ceiling back down into the room.


What sound does a fan make when it is turned on?

When a fan is turned on, it typically makes a humming or whirring sound as the blades rotate and circulate air.


How do the blades of a ceiling fan turn for cool air?

The blades of a ceiling fan create a cooling effect by circulating air in the room. They push the air downwards, creating a breeze that evaporation from our skin, making us feel cooler. This process helps to maintain a comfortable temperature in the room.


What energy transformation is in fan?

electricity to rotary mechanicalrotary mechanical to "wind"


When wind blows from behind a turning electric fan the fan will turn faster which means the fan consumes more energy but does the increased power come from the wind or the electricity or both?

Fan speed is the result of the impetus provided by the motor and the drag resulting from pushing the blades through the air. When the air through the fan blades already has velocity, the drag on the blades decreases...the motor power remains the same...so the fan speeds up. Current draw on the motor does not change.


How does a fan gives air?

A fan creates airflow by using rotating blades to push or pull air in a specific direction. As the blades spin, they move the air molecules around them, creating a breeze that is felt by people in the fan's vicinity.


Why sound will come for fan on rotating?

This relates to airflow in each of the fan blades. When the fan blades spin, the blades will catch the air and will start to vibrate as a constant process of being pulled back by the air and the blade's elasticity dragging it back to its previous position.


Why does air come down when a fan rotates?

The blades of the fan have a small angle tilt, so it can push down air.


Where would you find the inclind plane on a fan?

The inclined plane on a fan is typically found on the blades. The angled shape of the blades creates an inclined plane that helps to move air more efficiently as the fan rotates.
