What is the difference between a fan and a propeller..?
I don’t exactly agree with this, but Wikipedia [1] says a propeller is a type of fan which transmits power by converting rotational motion into thrust.
When I think of a ‘fan’, I think of the motor & the blades as a whole. When I think of a ‘propeller’, I think of only the blade portion. Otherwise, we would call an entire boat motor a propeller rather than just the rotating portion at the bottom…
In theory there is no difference, it is always a motor with a blade…but here we go with ways of describing things… it is widely accepted that the difference between the two is the way that you are looking at it or in other wards what is moving what; what it is stationary and what is moving: A fan is when the motor and blades are fixed and the moving part is the medium, for example air, and a propeller is when the motor and blades are moving and the medium is stationary like in a boat. Hope that this make sense to you NILO
The difference between the two is where and how you would apply it…for an instance, its grammatically correct to say “we’d use a fan to propel a boat”,however it is technically incorrect.
Both fan and propeller have the same geometrical features,however they differ in application…fans mostly seen on cooling towers,boilers,driers etc. and propellers on sea and other amphibious vessels.
