Surface area of elbow?

The formula for the surface area of an elbow (or 90° angle) is (pi^2 * (radius2^2 - radius1^2) ) / 4. Where pi = 3.14159, radius 2 = the radius from the center to the outside, and radius 1 = the radius from the center to the inside.


What is take off measurement for 90 degree 8 inch pipe?

The take-off for a standard radius 90 is one and one half the diameter of the pipe. Example: 6 inch 90 has a take- off of 9 inches. The take-off for short radius 90 would be the dia. of the pipe. Long radius 90 is 2 times the pipe diameter.
