I'm, sorry Senthil but I do not understand your question.

Are you asking about the length or angle of the reducing piece between two different size ducts?

Thanks for ur reply brain , I explain u

Duct Size : 26" x 12"

When the above duct connected to the mouth of the machine , with a size of 30" x 12 " , one reducer arise in between machine mouth and the duct.

I need to know the area of this reducer , one side
30" x 12" and another side 26" x 12"

What is it you are trying to calculate?

Reading your previous post you already got the sizes fixed.

The smallest area of your reducer will be the same as the duct 26"x12"=312 square inches.

Or are you after the losses in the ductwork?
