A fan does not have to possess an odd number of blades. The can have any number from two on up. Ceiling fans typically have 3 to 5 blades, with four being extremely common.

Why lot of dust is sticking to the wings of fan in a room?

Dust collects in closed areas and can often build up around the baseboards and on surfaces in a room. When there is airflow in a room, dust particles are sent airborne and land on many surfaces, including fan wings or blades.


What is the energy transfer for a solar powered fan?

heat energy is transferred/converted into kinetic and sound energy. Kinetic is usefull as it turns the wings and that is its purpose. sound energy is wasted as you do not need this


Why does a fan have three wings?

I do not really know, but it is noticable in the history of the airscrew (Propellor) on aircraft that they started with two blades, WW1, and then had 3 by WW2. By the end of WW2 4 bladed propellors were sometimes used. Now there are more variants still and of course Jet engines use many many vanes to propell the air into them. Another answer There would be multiple factors for deciding this. There are different fans and propellers that are designed for their specific used - does it want high velocity, like you might find in a plane? A regular three-blade fan is meant to go fast (for it's size). Here are some of the factors considered when designing a fan: -maximising energy output. Too many blades, and the fan is going to have to use more power to turn them. Too few, and it wont push enough air through. -optimising construction for production. Many blades is going to cost more. -having the most aerdynamic design. -minimising noise


Why does the fan on electric heating run non stop and doesn't heat the house?

It does heat the house slightly. The heating is equal to the number of Watts of the fan. Why does the fan run all the time even when to heating is on? Because it is a silly design or the activation switch is stuck on.


If a fan has 4 equally spaced blades what is the least number of degrees that you can rotate the fan onto itself?

With 4 equally spaced blades on a fan, you can rotate the fan onto itself with a minimum of 90 degrees. Each blade will align with the next blade at a quarter turn, which corresponds to 90 degrees.
