    (Metal-Casting Processes) (Groups) 10.47 A round casting is 0.2 m in diameter and 0.75 m in length. Another casting of the same metal is elliptical in cross-section, with a major-to-minor axis ratio of 2, and has the same length and cross-sectional area as the round casting. Both pieces are cast under the same conditions. What is the difference in the solidification times of the two castings? 10.48 A cylinder with a diameter of 50 mm and a height of 75...
