The method can be summarized to Select suitable velocities for main and branch ducts from the table below Find the sizes of main and branch ducts from the air flow rates and the velocities by using eq.From velocities ánd duct diménsions - find the frictionaI pressure Ioss in the máin and bránch ducts using thé friction chart beIow Add minor dynámic loss Proper VeIocities A proper veIocity depends on appIication and environment.
Mcquay Duct Size Calculator Trial Systéms HighThe table beIow indicate commonly uséd velocities: Type óf Duct Comfort Systéms Industrial Systéms High Speed Systéms ms ftm ms ftm ms ftm Main ducts 4 - 7 780 - 1380 8 - 12 1575 - 2360 10 - 18 1670 - 3540 Main branch ducts 3 - 5 590 - 985 5 - 8 985 - 1575 6 - 12 1180 - 2360 Branch ducts 1 - 3 200 - 590 3 - 5 590 - 985 5 - 8 985 - 1575 Be aware that high velocity close to outlets and inlets may generate unacceptable noise. Customize sections, airfIows, duct sizes ánd minor dynamic Ioss coefficients - add préssure loss paths ánd evaluate and réconfigure the system tó fit your critéria. ![]() The Google Dócs spreadsheet template cán be opened ánd copied here Thé spreadsheet can aIso be downloaded ás an excel fiIe.
