Question: riser takes 25 longer time to solidify than the casting...

Question details

riser takes 25% longer time to solidify than the casting then calculate the diameter of the riser. Problem 5(20 points) Total solidification times of three casting geometries are to be compared: (1) a sphere, (2) a cylinder, in which the length-to-diameter ratio 1.0, and (3) a cube. Volume 1000 cm3 for all three shapes, and the same casting alloy is used. (a) Determine the relative solidification times for each geometry. (b) Based on the results of part (a), which geometric element would make the best riser? (c) If the mold constant 3.5 min/cm2 in Chvorinovs rule, compute the total solidification time for each casting. 6:17 AM Ad ENG 019
