b) A sand casting process is to be performed using a certain alloy to produce a cube shaped casting with dimensions of 50 mm on each side. The molten metal is poured into the pouring cup of a sand mold at a steady rate of 1000 cm/s. The molten metal overflows the pouring cup and flows into the downsprue which has a height of 25 cm. The cross-section of the sprue is round, with a diameter at the top being 3.4 cm. The casting took 180 s to solidify. Determine: (i) the proper diameter at its base so as to maintain the same volume flow rate.
