lcoa Corporation (from Aluminum Company of America) is an American industrial corporation. It is the world's sixth largest producer of aluminum, with corporate headquarters in Pittsburgh, Pennsylvania. Alcoa is a major producer of primary aluminum, fabricated aluminum, and alumina combined, through its active and growing participation in all major aspects of the industry: technology, mining, refining, smelting, fabricating, and recycling. In a casting R&D trial of a certain aluminum alloy which performed in Alcoa Co, Ltd., by using a particular sand mold, it took 5 mins for a rectangular-prism shaped casting part (length=6 in, width=8 in, height=10 in) to solidify. Calculate the minimum solidification time of the cylindrical riser so that the riser will be effective by using Chvorinov's Rule. Use the following table for the dimensions of the cylindrical-shaped
