There is no correct exhaust area for different fans of the same size fan area, there are many variables that change performance, the only commonality is exhaust area.

Odysis is mostly correct from my glance thru his posts and we have discussed a lot of this in the past.

The duct changes the physics for props as it defines exactly how much volume moves thru for every rpm the rotor turns.

If anyone wants wants links to all of Klaus Schornhorst postings I have it at home and will post them tonight.
