Nov 12, 2006 #5 willard3 Mechanical Jan 14, 2006 1,437 0 0 US There is really no formula for fan sizes. There are many fan blade types (radial, backward inclined, forward curved, axial and etc) depending upon the use for the fan.

Nov 23, 2006 #7 stanlsimon Mechanical Feb 14, 2005 177 0 0 US There are probably some theoretical formulas for fan air flow. However the fan manufacturer's literature is the place to start. You need to know how much air you want to move and what static pressure rise the fan is required to develope. Upvote 0 Downvote
