Problem 2. Ga-Sn alloy is poured into a sand mold. The level of the metal in the pouring container (pouring cup) is 10 inches above the level of the metal in the mold, and the channel is circular with a diameter of 0.4 inches. • 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 per side and a height of 4 inches (this means that the volume of the casting is 144 in3, with a constant cross-sectional area of 36 in?)? Assume that the sprue is frictionless. • Explain what would be the difference during solidification between this alloy and pure gallium with the help of a small diagram. Assume that the Ga-Sn alloy has a density of 5.887 g cm-3* and a viscosity of 0.682 Pa-s*.
