Duct sizing
Is there a forumla for finding the duct size if you know the cfm and the pressure drop? Example (What size metal duct should be used to deliver 290 cfm with a pressure drop of 0.12 if the total length is 80 ft.) I have always used a duct calculator to find this out,but a friend said that there is a forumla for this.
