Pure aluminum is poured into a sand mold. The metal level in the pouring basin is 8 in. above the metal level in the mold, and the runner is circular with a 0.25 in diameter. The viscosity of the metal is 1.5e-07 lb-s/in2 and its density is 0.098 lb/in3.g = 32.2 ft/sec^2 a) Calculate the velocity of the metal when it gets into the mold. b) Calculate the flow rate of the metal when it gets into the mold. c) Calculate the Reynolds number (Re = velocity*diameter* density/viscosity).
