Wardner asked what the tip speed should be on a 60" snowblower with an 18" blower wheel and I started out by saying typical snowblowers a little larger run the fan at standard PTO speed of 540 RPM's so the smaller one would need to run a bit faster.
Some others guessed as high as 1000, or, I believe even 1200 RPM's.
I emailed the sales guys at Quick Attach Attachments, Inc. asking what the fan speed was on their UTV model, which is 60" wide and has only a 16" fan.
Their reply...
"HI BOB,
THE FAN SPEED IS BETWEEN 700 AND 800 RPM. GIVE ME A CALL IF YOU HAVE FURTHER QUESTIONS.
THANKS FOR CHECKING US OUT."
So, using a average speed of 750 RPM's and a fan diameter of 16" tip speed would be about 3140 feet per minute.
(16" X 3.14 = 50.24" = 4.18667' X 750RPM = 3140 feet per minute.)
Working that out for the 18" fan:
3140'per minute/4.71' = 666.67 RPM's
(18" X 3.14 = 56.52" = 4.71' X 666.67 RPM's = 3140 feet per minute tip speed.)
