Ed,
I did some plotting, and here is what I came up with:
The red line is a straight sided square duct,
Light blue is the exponential Horn duct square,
Brown is the streamline duct square.
I don't know if the exponential horn differs enough from a straight line to make a difference.

In a former life, I built exponential horn loudspeakers for concert sound systems. The rate of expansion was much greater than what's shown on the graph. Perhaps the loading of the heat exchanger alters the formula, but at first glance, something doesn't look right.
