A jeweler wishes to produce 20 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 located in four rows, each 15 mm from the other on the sprue. The rings require a 3-mm diameter, 12-mm 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.
