output

[windspeed]

Can someone tell the answer to this, couldnt find a chart

what would be the output of Dans 10 ft dual rotor in clean wind 13 mph

windspeed

[Flux]

I doubt that anyone can answer this with any degree of certainty.

I will make a guess at about 180W.

I assume you mean a spot figure at 13mph. If you mean average power at 13mph average windspeed then a fair bit higher due to the Rayleigh distribution.
