A2. Assuming you refer to the diameter of air handling ducts, then the cross - sectional area will increase as the square of the diameter. A 10" duct will have an area of pi x (10^2)/4. A 6" duct will have an area of pi x (6^2)/4. I'll leave you to the math.

A1. Well if 6 i ducts= 12 ducks, then I would assume that 6 in ducts can roughly equal a ceramic duck.
