78.5” square inches. For this example, we will try a 6” diameter duct: 0.78539 x 36=28
If we multiply the cross sectional area of the 6” duct by 3 duct outlets : 28 x 3= 84”. 84 is greater than 78.5 so
the 6” ducting split into 3 ducts is acceptable. Some form of dampening may have to be used to balance the
output of different sized outputs.
