To calculate the weight of an 8-foot long precast concrete culvert pipe with a 36-inch outside diameter and a 4-inch wall thickness, you first determine the pipe's volume. The outside diameter is 36 inches, and the inside diameter is 28 inches (36 - 2 * 4). The volume can be calculated using the formula for the volume of a cylindrical shell. The density of concrete is typically around 150 pounds per cubic foot, so you can multiply the volume by this density to find the weight. The total weight will be approximately 1,200 to 1,300 pounds.
take the outside diameter and subtract the thickness twice.
nominal diameter is the original diameter of an object
NB (nominal bore) is the European designation equivalent to NPS is DN (diamètre nominal/nominal diameter/Durchmesser nach Norm), in which sizes are measured in millimeters. NB (nominal bore) is also frequently used interchangeably with NPS.You can refer more details herehttp://www.piping-engineering.com/nominal-pipe-size-nps-nominal-bore-nb-outside-diameter-od.html
The purpose with a pipe is the transport of a fluid like water, oil or similar, and the most import property is the capacity or the inside diameter. For a ASME/ANSI B 36.10 Welded and Seamless Wrought Steel Pipe the inside diameter - ID - of a NPS 2 inches pipe with * schedule 40 is 2.067" * schedule 80 is 1.939" The inside diameters are close to 2" and the nominal diameter related to the inside diameter. Outside diameter are 2.375" for both schedules. Since the outside diameter of a single nominal pipe size is kept constant the inside diameter of a pipe will depend on the "schedule" or the thickness of the pipe. The schedule and the actual thickness of a pipe varies with the size of the pipe. It is common to identify pipes in inches by using NPS or "Nominal Pipe Size". The metric equivalent is called DN or "diametre nominel". The metric designations conform to International Standards Organization (ISO) usage and apply to all plumbing, natural gas, heating oil, and miscellaneous piping used in buildings. The use of NPS does not conform to American Standard pipe designations where the term NPS means "National Pipe Thread Straight". Nominal Bore (NB) may be specified under British standards classifications along with schedule (wall thickness). The tolerances are looser to pipes compared with tubes and they are often less expensive to produce. The nominal dimensions of tubes are based on the outside diameter. If we look at Copper Tubes - ASTM B88 the outside diameter of a 2" pipe is 2.125", relatively close to 2". The inside diameter of a tube will depend on the thickness of the tube. The thickness is often specified as a gauge. If we look at Copper Tubes - ASTM B88 the wall thickness of 0.083"of a 2" pipe is gauge 14. The tolerances are higher with tubes compared to pipes and tubes are often more expensive to produce than pipes.
Tube is measured by outside diameter, pipe is measured by inside diameter.

It could be 65" (b wall - 5.5" wall thickness), or 66.5" (c wall - 6.25" wall thickness).
The formula to calculate the outside diameter of a circle is: outside diameter = diameter + (2 * thickness). This formula takes into account the thickness of the circle's material when calculating the overall dimension.
30-inch (inside diameter) RCP has a wall thickness of 2.75 inches. Therefore, the outside diameter of 30-inch RCP is 35.5 inches.
To calculate the outside diameter of a steel coil, you first need to determine the inside diameter (ID) and the thickness of the steel material. The outside diameter (OD) can then be calculated using the formula: OD = ID + 2 × thickness. If the coil is wound in layers, you may also need to account for the number of layers by adding the thickness multiplied by the number of layers to the ID.
Outer radius minus inner radius Subtract the inside diameter from the outside diameter, then divide the difference by 2.
That would depend on the wall thickness of the pipe. 54 inches is the outside diameter so subtract the pipe wall thickness (x2) adn you have the inside diameter.
-length-outside diameter of shaft-wall thickness
For example a tube (hollow cylinder)with wall thickness 't' the outside diameter is: 1.00+2t So if the walls are 1.0mm thick the outside diameter is 1.20cm If there is no wall thickness the inside and outside diameter are the same. This seems a little too simple a question to ask here so I suspect the person asking the question has omitted some details or that they want an answer to a different question.
It depends on the thickness of the material that the pipe is made from.
