A fan converts mechanical energy in the form of a rotating shaft, into mechanical energy in the form of kinetic energy of the fluid medium (usually air), by means of a pressure differential.
Which energy is used in fan?
A fan is a device that utilizes the mechanical energy of a rotating impeller to produce both movement of the air and an increase in its total pressure.
What type of energy is a fan blowing?
It gets turned into kinetic energy of electrons, which is the electrical current that flows to your house. This electrical energy turns a motor in your fan, which is kinetic energy of the motor/fan blades.
Why is a fan mechanical energy?
We know that an electric fan as the name suggests runs with electricity and it functions due to mechanical energy i.e. its rotational motion. Thus, an electric fan converts an electrical energy into mechanical energy.
Is a fan an example of mechanical energy?
For example, when we switch on the fan, the electric motor starts converting the electrical energy into mechanical energy. The mechanical energy then gives the fan blades the ability to do work and hence, they start rotating.
Where is the energy going in an electric fan?
When we switch on a fan, the fan converts a significant portion of the electrical energy into kinetic energy of the fan blades. Some part of electric energy is converted into heat. So the correct energy transformation will be: Electrical energy → Kinetic energy.
What are the examples of electrical energy?
Here are some examples of everyday objects that use electrical energy.
- Washing machine.
- Cell phone.
- Air conditioning system.
- Heating system.
What are examples of energy transformation?
What are some examples of energy transformation?
- The Sun transforms nuclear energy into heat and light energy.
- Our bodies convert chemical energy in our food into mechanical energy for us to move.
- An electric fan transforms electrical energy into kinetic energy.
What is a example of radiant energy?
Examples of radiant energy include the warmth that radiates from a hot stove and the warmth from direct sunlight. This electromagnetic wave can be seen in figure 1. Not all radiant energy is visible (see figure 2).
