– Wrap a string around the pipe.
– Mark the point where the string touches together.
– Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
– Divide the circumference by 3.14159.

Subsequently, How is black pipe diameter measured?
Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS). … For example, a 1-1/2″ pipe size actually has an outside diameter of 1.9″ NOT 1.5″.
Also, How do you find the outside diameter of a pipe?
– Wrap a string around the pipe.
– Mark the point where the string touches together.
– Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
– Divide the circumference by 3.14159.
What is the outside diameter of a pipe?
The outside diameter of a pipe or any cylinder is exactly what it sounds like – the distance from one outside edge of the pipe to the opposite outside edge, measuring straight across the face of the pipe or across a cross-section that runs perpendicular to the pipe’s long axis.

What is outer diameter of pipe?
Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS). Although it is related to the outside diameter, it is significantly different.
How do you measure the diameter of a pipe?
– Direct Diameter measurement is the easiest. Measure at the end of the pipe. …
– Direct Diameter measurement with a caliper (useful if the end is not accessible) 1 1/2″ pipe.
– Measure circumference using a flexible tape and divide the outside circumference by 3.1415.
Is black pipe measured ID or OD?
Pipes are measured by the Inside Diameter I.D., versus tubing which is measured by the Outside Diameter O.D.
What is the diameter of pipe?
Measure circumference using a flexible tape and divide the outside circumference by 3.1415. Here the circumference is about 1/32″ (0.03″) less than 6″ = 5.97″. So 5.97 ÷ 3.1415 = 1.900″ diameter – 1 1/2″ nominal pipe.
How do you measure the diameter of PVC pipe?
– Look at the end of a piece of PVC pipe.
– Find the widest point across the opening.
– Measure from the outside edge of the pipe to the opposite outside edge.
– This measurement is the outside diameter or “OD” of the pipe.

How is OD calculated?
For absorbance measurements, the optical density (O.D.) is a logarithmic measurement of the percent transmission (%T) and it can be represented by the equation, A = log10 100 / %T.

What is the outside diameter?
The outside diameter measures the distance of a straight line from one point on the outside of the object, through its center, and to an opposite point on the outside. The internal diameter measures the inside of the object.
