A jeweler wishes to produce twenty gold rings in one investment-casting operation. The wax parts are attached to a wax central sprue with a 20 mm diameter. The rings are in four rows, each 15mm from the other on the sprue. The rings require a 3 mm diameter, 12mm long runner to the sprue. Estimate the weight of gold needed to completely fill the rings, runners, and sprues. Assume a typical ring has a 25 mm outer diameter, 19 mm inner diameter and 5 mm width. The specific gravity of gold is 19.3.
