Fan Design
Fan Design
(OP)
I am studying on the Open University and for my project I am researching the topic of extractor fans, mainly the ones found in the home i.e. kitchen, bathroom etc.
I was wondering if anyone could help me out with any calculations or know of a website that can help me i.e. blade angles, pressures required, speed of fan, forces etc. that are needed to come up with a suitable presentation.

RE: Fan Design
be capsulised in a paragraph or two.
First, decide what flow is needed and what pressure drop must be overcome. These two combined and an assumed fan efficiency will give you the power required. Then you can choose a motor to meet the power need. The motor will probably be an induction type with
a narrow range of speeds for best efficiency.
Select a working rpm. Then calculate specific speed.

Enough from me. Get ahold of Steppanoff's book "Turboblowers" for more info. Or contact me directly.
