There are two equations for determining a Duct’s Cross-Sectional Area. One to be used for square or rectangular duct and the other for round duct. The equation for a square or rectangular duct is: A = X x Y The equation for a round duct is: A = π x r² A: Duct Cross Sectional Area X: Height in feet Y: Width in feet r²: Radius of the duct in feet If we have a round 14" diameter duct, the radius is half that, or 7" which converts to 0.585 feet (7"/12"). Substituting our values into the equation we see that the Duct Cross Sectional Area equals pi, or 3.14159 times our radius, .585 squared giving us a solution of 1.07 square feet. A = π x 0.585² A = 1.07 sq. feet #FanCfmCalculation #FanCFM #HowToCalculateFanCFM #CentrifugalFanCFMCalculation #VolumeFlowRate #FanDischargeRateCalculation https://www.facebook.com/zishan.anwar...
