Hello, The following is from the ABS 2006 Help file: Titled: "Assigning an ASHRAE fitting number using the Properties palette" The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) publishes a database that includes loss coefficient tables for many duct fittings. increases as a result of mixing. The loss in total pressure and the local loss coefficient can, therefore, also have negative values for the lower velocity jet (Idelchik et al. 1986). Duct Fitting Database. A duct fitting database, developed by ASHRAE (1994), which includes 228 round and rectangular fittings with the provision to. The most advanced work in developing and collecting C-coefficients was done by Idelchik and Steinberg (1994) ref184. A Computer Duct Fitting Database (DFDB) was developed by ASHRAE in 1993 (ASHRAE, 1994). The DFDB includes 228 fittings organized by fitting function (supply, exhaust, common), duct shape. b See Figure 16. c Duct lengths are to fitting centerlines. d See Table 12. e Duct pressure based on a 0.09 mm absolute roughness factor. f Pressure drop based on manufacturers ' data.
