I desire to create a very powerful wind tunnel which will pull an incredible amount of air through a 2 inch hose 300 ft long. At this time, I have a 10 inch diameter pipe which I plan on mounting an airplane prop which could turn 9000 rpm. This prop will be pulling air from an enclosed steel box 4 ft high by 4 ft wide by 2 ft deep. I plan on using a 10 airplane propeller. Should I use more than a straight 2 blade and what pitch? Thank you for your help.
