Windspeed from the fan..

[pemz0r]

Does anyone know the wind speeds generated from the spinning fan at different RPM's?

Is there a test behind this line of questioning? J/K. What has your curiosity so peaked about he actual speeds?

heres a start 5 Blade fan vs. 11 Blade Fan

This is all documented in Bruce Anderson's book if you have a copy.

pemz0r,

Your in Newport Beach. Head down to the harbour. Many of the hotdog sailors have hand-held anemometers. Just hold one near the fan and see what it reads at various rpms.

I don't think anyone calculates wind speed when they test the fans. All the graphs and data show volume of air for the various speeds.

If I remember correctly the 11 blade fan was moving something like 1400 or 1500 liters of air per second at 7000 rpm. I know that people have posted some real nice graphs that show the flow across the RPM range.

just curious, that's it.

Thanks everyone
