(Pi*(Center of elbow - od/2)^2-(pi*(Center of elbow+od/2)^2)÷4)÷100000=0.221 Square Meter
measure the length of the fitting first. Then insert pipe into fitting and mark a line on pipe. measure that bit of pipe. deduct off the length of fitting and half it to give you your x dimension
The width of a circle such as a cross view of a pipe.
to divide a pipe into sections measure the outside diameter then multiply by 3.142 this will give you the circumference divide this number by how many sections you require place a mark anywhere on the on the pipe then measure from that mark your answer The best method for calculating the cross section area of a round pipe or tube is to use the following formula: ((D-W)*W)*PI Where as D= Outside Diameter Measurement W= Wall Thickness PI= 3.1416 that is circumference. The answer I have is: diameter squared x .7854 Ex. 3inch pipe (inside diameter) 3 x 3 x .7854= 7.0686
If a center finder is not available, you can use a method called "scribing." First, measure the diameter of the pipe and divide it by two to find the radius. Then, use a straight edge or a ruler to draw a line across the pipe at the measured radius on both sides, creating two intersecting points. Finally, connect these points to accurately mark the centerline of the pipe.
pipe is measured up 12 inchs I.D. inside 12 and above are measured by O.D.if you measure 10" pipe you measure it from inside..12" and above measure from outside diametor
Measure the outside diameter of a pipe with some calipers. If you don't have these then you can get a good idea by using a ruler or tape measure, making sure to go through the mid point. It's outside wall to outside wall.

OD is Outside Diameter - at least when you are talking about pipe...
id means inside diameter, od means outside diameter, copper pipe and tubing is measured by the od, therefore the od the pipe or tubing will be the same as the id of the fitting
14" and above
89mm
Can you calculate the ID of a pipe when you have the OD to be 10.75" and the wall thickness to be 0.5"Depends on what you know about it. If you have the outer diameter and you know the wall thickness, then ID = OD-2 x wall thickness
NB = inside diameter of the tube. OD = outside diameter of the tube.
The outside diameter (OD) of a 40-inch nominal bore black steel pipe is typically 40 inches, as the nominal size refers to the approximate internal diameter of the pipe. However, the actual OD for standard pipe sizes can vary; for a 40-inch nominal bore, the standard OD is approximately 42.16 inches according to the American National Standards Institute (ANSI) specifications. This discrepancy is due to the wall thickness of the pipe, which is accounted for in the nominal size.
what is difference between NB & OD in pipe size
