THANK YOU SIR FOR YOUR VIDEO I HAVE A QUESTION FOR RECTANGULAR DUCT REDUCER FORMULA AFTER CALCULATE THE w+h , THE w1x h1 NO NEED TO ADD INTO THE CALCULATION FORMULA? A=1.92M2 is complete size of this reducer? Thanks

[@ncengineeringtechnology3376]

Yes You need to consider the largest dimensions, it is the estimate of sheet used for duct fabrication.

[@rajamohamed9119]

On which standard this calculation is approved (eg. Smacna or Ashrae)???

[@ncengineeringtechnology3376]

For fabrication you need to follow SMACNA or ASHRAE standards, It is for the cost, it is the estimate of sheets that used for the fabrication of duct, used for invoicing.
