The take off formula of a 45 degree elbow pipe, will depend on what the pipe is on. Sometimes a 45 degree pipe will need a 90 degree right angle turn to come off.

Elbow
The formula to calculate the surface area of a 90-degree elbow is A = πDL, where A is the surface area, D is the diameter of the elbow, and L is the centerline radius. The surface area of the elbow is essentially the curved surface area of the elbow pipe fitting. This formula is derived from the mathematical principles of geometry and calculus, specifically the surface area of a cylinder.
Need more information, but here are some examples for pipe elbows; you need to enter the elbows' centerline radius: 10" steel pipe with a 2R or 10" radius: if it is a 90 degree ell C/L-to-END is 10"; for a 76 degree ell it is 7.81" 10" steel pipe with a 3R or 15" radius: if it is a 90 degree ell C/L-to-ENC is 15"; for a 76 degree ell it is 11.72" The way to calculate this is to draw a right triangle with the smaller angle being 38 degrees (half of the 76 degree angle). The length of the triangle's "side adjacent" to the angle will be the length of the ell's centerline radius (15" in the case of the above 3R elbow). Multiply the tangent of the angle of 38 degrees by the length of the ell's centerline radius to get the length of the ell's "centerpoint-to-end" length.
