How do you calculate square footage of a pipe?
To calculate square footage of a pipe you need to use the area formula of a circle, a=1/2bh. then find the circumference of the entire pipe.
What size pipe is a 5 inch circumference?
The formula for working out the circumference of a circle (like a pipe) is diameter times pi. (You should find pi on your calculator, if not, it is 3.14159265) Since you know the circumference, you divide the circumference (5inch) by pi (3.14159265), and you get the diameter, i.e. the size pipe. While the above formulas are correct, using this equation example will not tell you what size pipe you have. There are a number of factors involved in determining the correct answer. There are many different materials that pipe is made out of and some of these affect the dimensions of the pipe. As an example, the actual outside diameter of 1" copper pipe and 1" steel pipe are not the same. If you are talking about steel pipe, it is important to understand that all pipe 12 inch and under is referred to as "nominal" pipe size. In this case, the outside diameter of 12 inch pipe is actually 12.75 inches. For the original question asked above, the 5 inch circumference would equal 1-9/16" outside diameter which would be the equivalent of 1-1/4" pipe (nominal).
What is the outside circumference of a 15 inch pipe?
It is 47.1 inches.
What is the outside circumference of a 36 inch pipe?
The answer depends on what the "36 inch" measures: inside circumference, radius, diameter?
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.
How calculating weight of pipe?
Find the circumference of the exterior of the pipe, then find the circumference of the interior. subtract the two to find the thickness of the pipe. then multiply the length of the pipe. Now you have the mass of the pipe, so calculate that into the weight of steel or aluminum or whatever the pipe is made of.
How do you calculate square footage of a pipe?

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 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
What is the circumference of a six inch pipe?
circumference = 2*pi*radius or pi*diameter
What size pipe is a 5 inch circumference?

What is the circumference of a pipe 10 inches in diameter?
31.4159inches
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 15 inch pipe?
It is 47.1 inches.
What is the formula of finding the circumference of the pipe?

Pipe with circumference 6 centimeter and length 20 centimeter and that 10 turns of a wire are wrapped around the pipe. what is the length of the wire?
To find this you need to imagine the pipe slit straight down and rolled out. At this point what you have is 10 right triangles, with the base of the triangle being the circumference of the pipe and the height of the triangle being the height of the pipe divided by the number of wrappings. The hypotenuse then is the length of one wrapping. Multiply that number by the number of wrappings and voila, you have the length of the wire.
