Why do you measure the diameter of the pipe instead of the circumference of the pipe?

You could, but if you do, you will have to divide the circumference by π, and that's an irrational number. And, think of placing the pipe in a rectangular box with two sides the same length as the diameter of the pipe. It fits, and it makes the question much, much simpler. (Doesn't it? Sorry if my answer's too long.)

How would a plumber measure the diameter of a pipe?
They can measure the circumference of the pipe and divide it by pi or 3.14 to get an approximate answer
What is the outside circumference of a pipe if the inside diameter is 1.5 inches and the thickness of the pipe is .25 inch?
The pipe will have an outside diameter of 1.5+.25+.25 = 2". A pipe with an outside diameter of 2" has an outside circumference of 2"*Pi. 2"*3.142 ~= 6.284" or about 6 1/4"
What is the formula of finding the circumference of the pipe?
diameter times 3.14159
How do you calculate for outside diameter for welding math?
Since the circumference of a circle is equal to its diameter times pi, the o.d. of a pipe is equal to its exterior circumference divided by pi.
How do you calculate inch diameter for reinforcement pad in pipe?
Reinforcing pads mirror the pipe that they are being welded to in size, thickness, and material. To measure the diameter of the pad, measure the pipe at a cross section.
How would a plumber measure the diameter of a pipe?
They can measure the circumference of the pipe and divide it by pi or 3.14 to get an approximate answer
How do you find the circumference of a pipe?
Measure the inside diameter and multiply it by 3.14159 (pi)
What is the circumference of a pipe 10 inches in diameter?
31.4159inches
What is the circumference of a six inch pipe?
circumference = 2*pi*radius or pi*diameter
What formula is used to find diameter when you know the circumference of a standard copper water pipe but not it's thickness?
Circumference divided by pi equals diameter. Pi X Diameter=Circumference.
What is the outside circumference of a pipe if the inside diameter is 1.5 inches and the thickness of the pipe is .25 inch?
The pipe will have an outside diameter of 1.5+.25+.25 = 2". A pipe with an outside diameter of 2" has an outside circumference of 2"*Pi. 2"*3.142 ~= 6.284" or about 6 1/4"
What is the formula of finding the circumference of the pipe?
diameter times 3.14159
How do you calculate the cross sectional area 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
What is the outside circumference of a 36 inch pipe?
The answer depends on what the "36 inch" measures: inside circumference, radius, diameter?
How do you calculate for outside diameter for welding math?
Since the circumference of a circle is equal to its diameter times pi, the o.d. of a pipe is equal to its exterior circumference divided by pi.
What is the circumference of a 4inch pipe?
"4 inch" would usually refer to the diameter in such cases. You can multiply that by pi (which is about 3.1416) to get the circumference.
What is the circumference of 12-inch pipe?
The circumference of 12-inch pipe is: 37.7 inches. (C = d x Pi)Since 12 inch pipe is a nominal size and its outside diameter is 12.75 inches, the circumference of 12 inch pipe actually is : 40.035 inches
