Yes, but for insulation you need to increase each dimensions by insulation thickness. if duct width is 500x300 mm & insulation thickness is 50 mm, then for insulation you can consider size as 550x350 mm.
Yes, it will not give you actual surface area of duct, but it will give you the estimate of sheet used for duct fabrication, almost all companies use same calculation for invoice.
Hello. I'm new to this field. I have a question can I use this calculation to calculate the duct insulation I will need to cover a duct? Thanks.

@@ncengineeringtechnology3376 Can I use this calculation to calculate the area of the metal sheet for price/m2? thank you sir.

Duct is not fabricated how can we determine L1& L2
Can i request for the excel for file?
its wrong calculation
Transition piece calculation is wrong.. why didn’t you consider dia of round side..?
