The wall thickness of 4" Sch 40 pipe is 0.237 inches.
The outer diameter is 4.5 inches and the inner diameter is 4.026 inches.
4" Sch 80 BI pipe is .337 inches thick

The wall thickness and whether it has an ASTM certification There is XHCI uncoated Standard weight No Hub
By knowing what TYPE of pipng such as cast iron/ Steel / plastic /WALL THICKNESS / copper / TYPE of copper as each type K/ / M /DWV / ACR all have a different wall thickness thus different restrictions
What medium and temperature as there is something called "pressure temperature relationship"
Demo a section of the wall.
Black iron pipe is used for gas installations but ONLY if the piping is indoors. Outdoor gas piping is usually done in galvanized pipe. Steam is also piped with black pipe, fire sprinkler and standpipe systems also use black pipe.
What schedule 10 ,20, 40, 80, 120????
Schedule 40 and schedule 80 have the same outside diameter (OD). The wall thickness is greater on schedule 80 than it is on schedule 40. So on schedule 80 the inside diameter (ID) gets smaller.

That would depend on the wall thickness everything being equal cast is heavier
Through cast Iron radiators and copper tubing and schedule 40 black steel piping
Yes and it can be schedule 80 and schedule 120
In iron materials ,during the critical thickness of it the ironoxide grows inside the material. This thickness where it happens is called critical thickness.
An iron equates to 1/48th of an inch.
