Formula: Length = volume/area Area = Pi * (diameter * diameter)/4 Volume = Weight/density Lead density = .4097 lb/cu-in Weight (lbs) = Grains/7000 Note: A Windows computer program on CD-ROM, called DC-LEAD, is available for $10. It calculates lengths, weights, extrusion pressures for any diameter and lead hardness, and determines the size of cylinders, extruder bores, billet weight, total wire length, drive pressure and ram thrust for building lead wire extruders. Order the Windows version directly from Corbin. |
