Hi, i am new in this tool; but i want to make the next exercise:
To obtain the thickness of the steel sheet, in base of the width of the duct and his system type.
If System Type is high velocity and the width is:
< or = 12" caliber 26
(>12") OR (< or = 30" ) caliber 24
If System Type is low velocity and the width is:
< or = 18" caliber 24
(>18") OR (< or = 48" ) caliber 22
This with each range of width of duct and velocity.
If you have any coment, thanks.
