Pipe bending computations made with hand-held calculator
"The following program (Table 1), written for the Hewlett Packard 41C/CV calculator, addresses the geometry of fabricating offset bends, sloping scraper traps, connections and direction changes common to all pipelines. Minimum code radii are calculated for each size of oil or gas line. The vertical distance between below and above ground center lines is matched to a design distance with given tangents (5 ft is a convenient tangent for pipe bending machines). The bend angle, overall horizontal distance, and total length of pipe are calculated for each configuration."

BEST!
