The cut length for the pipe is 35 and 1/4
inches and bend angle is 40.46°. Included
in the outputs are the arc lengths to be used
to cut your butt weld elbow to the calculated
bend angle. These are inner arc length of 4
and 1/32 inches, center arc length of 6 and
11/32 inches, and outer arc length of 8 and
