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

To calculate the surface area of a pipe fitting, you need to first determine the individual shapes that make up the fitting, such as cylinders, cones, or spheres. Then, calculate the surface area of each shape using the appropriate formulas (e.g., for a cylinder, the formula is 2πrh + 2πr^2). Finally, sum up the surface areas of all the individual shapes to get the total surface area of the pipe fitting.
(Pi*(Center of elbow - od/2)^2-(pi*(Center of elbow+od/2)^2)÷4)÷100000=0.221 Square Meter

1) pi x 36 square inches = area of a cross section of a 12 inch (round) pipe (the radius is 6 inches). 2) There are 144 square inches in a square foot (1 ft x 1 ft = 12 in. x 12 in. = 144 square inches) So, the area of a cross section of a 12 inch pipe is (pi x 36)/144 = pi/4 square feet.
The width of a circle such as a cross view of a pipe.
