engineering recuitment GATE ME 2023-24 Test Series Production Engineering (Manufacturing) Metal Casting Design of Gating System
A schematic diagram of the poring basin and the sprue of a gating system is shown in the figure. The depth of molten metal in the pouring basin is 100 mm and the height of the sprue is 1,500 mm.
Considering the cross-section of the sprue is circular, the ratio d1:d2 to avoid aspiration is
