Average and local heat transfer coefficients and flow friction data are reported for a rectangular horizontal duct 2.6- by 1.72-in. cross section and 13.5 ft. long. Variables include a range of Grashof numbers from 5 x 10/sup 4/ to 5 x 10/sup 5/ and Reynolds numbers from 1,000 to 10,000, all based on equivalent duct diameter. Axial wall temperature distributions, duct position, and inlet shape were varied. Average heat transfer coefficients and duct friction factors were correlated for both linear and nonlinear axial wall temperature distributions using a free-convection correction factor. (auth)
