Abstract
Methods, systems, and apparatuses for high efficiency exhaust duct flow path. In an embodiment, an exhaust duct flow path may be created by calculating the efficiency of an exhaust duct flow path with an initial measurement. The initial measurement may be changed and the efficiency analyzed. Then the efficiency of the exhaust duct flow path with the changed measurement may be compared to the efficiency of the exhaust duct flow path with the initial measurement.
