I found this fan, brought it back to life. The rated power is 250 W @ 240V and 2 A, which would get a power factor of 0.5, thought it has to be at least 0.75 or so?
I measured 540 W. The air velocity is about 20m/s, it should do 600L/s. But with wind energy formula and surface not know one could essentially calculate any power output between 80 and 900W, no idea, if the 250W mean the mechanical power output in terms of air moved?
Thanks for your ideas,
