are taken at a sweep angle θ passing through said section origin and measured from a first plane defined by said inlet end and increasing toward a second plane defined by said outlet end, said first plane and said section planes intersecting at an angle origin line about which said angle θ is measured, said X and Y coordinate values are determined relative to the section origin at a substantially central geometric location within each respective section, and said Z coordinate values are measured along a Z-axis extending perpendicular to said first plane, and having an origin at the center of said generally circular inlet opening and increasing toward said outlet end. 13.

The transition duct of claim 12, wherein the distance between said angle origin line about which said angle θ is measured and said inlet origin at the center of said generally circular inlet opening is approximately 1223 mm. 15. The transition duct of claim 12, wherein said coordinates X, Y and Z represent unitless scaled values. 16. The transition duct of claim 5, wherein said outer side of said third section comprises less curvature along a length of said outer side between said first and second sides of said third section than a curvature of said outer side of said second section. 17. The transition duct of claim 16, wherein said inner side of said third section comprises less curvature along a length of said inner side between said first and second sides of said third section than a curvature of said inner side of said second section. 18.
