Seems like you could get a pretty good ballpark estimate of fan power requirements from an ordinary household fan of the same diameter.

The belt is between 98% and 99% efficient.
The fan does not stop when the clutch is disengaged. The viscous clutch always spins the fan at 20% to 50% of pulley speed.
The blades of a household fan use a much shallower angle of attack.
