Ga-Sn alloy is poured into a sand mold The level of the metal in the pouring vessel (pouring cup) is 10 in. above the level of the metal in the mold, and the channel is circular with a diameter of 0.4 in. .What is the velocity and flow rate of the metal into the mold?Is the flow turbulent or laminar?How long would it take the sprue to feed a casting with a square cross section of 6 inches on each side and a height of 4 inches (this means thatThe volume of the casting is 144 in³, with a constant cross-sectional area of ​​36 in, and? Assume that the sprue is frictionless.• Explain what would be the difference during solidification between this alloy and pure rooster with the help of a small diagram.Assume that the Ga-Sn alloy has a density of 5.887 g cm3 and a viscosity of 0.682 Pas."T Gancarz Density, surface tension and viscosity of Ga-Sn alloys, J Mol Liq 241 (2017) 231-236
