I am looking for a chart that gives fan (propeller) cfm, according to dai, rpm and pitch. Thanks lots, Ray.

Ray, since each fan is slightly different you will probably have to get the manufacturers curves.

To be specific what I have is a 2 wing 38Deg. 14" dia blade. Wanted to know how many cfm it move at 1150 rpm at any given sp. and and then I could match it up to a 3 wing with lesser pitch. Not rocket science but I need a base line
Two wing blades are hard to come by. And that is a lot of pitch. At first glance thought it was 45 deg till I measured it.
