Consider casting sand mold of the piece shown in the figure. The
dimensions are in centimeters.
(i) The molten metal overflows the pouring cup of the mold and
flows down the sprue (downsprue) at a constant rate of 2000
cm3/s. The cross section of the sprue is circular, with
a diameter of 6 cm at the top....

(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...
