In this video we teach you how to size return duct work using velocity. We use a duct calculator or duct sizer to adequately design flex duct at 400 fpm. On the duct calculator, or duct sizer we also account for a 4% compression which enables duct designer to oversized flex duct to account for air resistance inside a relaxed flex duct liner. On this 4 ton Goodman furnace, we need 400 cfm per ton. That equals 1600 cfm. Enjoy the video! Happy Duct designing! For our full Duct Design Kit head over to our website at HVACdoubleagent.com
