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....
1) Turbulence during pouring of the molten metal is undesirable since (two best answers): a) it causes discoloration of the mold surfaces, b) it dissolves the binder used to hold together the sand mold, c) it increases erosion of the mold surfaces, d) it increases the formation of metallic oxides that can become entrapped during solidification, e) it increases the mold filling time, and f) it increases total solidification time 2) Total solidification time is defined as a) time between...
