A aluminium alloy casting has a cylindrical geometry with 100mm in diameter and weighs 3200 gram. This casting takes 7.5 min to completely solidify. Another smaller and lighter cylindrical-shaped casting with the same diameterto-length ratio weighs 1800 gram. This casting is made of the same aluminium alloy and the same conditions of mold and pouring were used. Determinea) The mold constant in Chvorinov’s Rule,b) The dimensions of the lighter castingc) The total soldification time of the lighter casting. The density of aluminium alloy= 2.7 gram/cm3and n=2

The below product in Figure Q1 requires to be sand casted based on the dimensions given. The past records revealed that a cylinder with a diameter of 1.5m with a height of 3m solidifies in 3 minutes in a sand casting operation using a similar material. a) Calculate the process time required for this design below. b) Suggest a suitable design of the riser. Specify what would be the riser dimension be in order to cater for this design. Justify your answer for the minimum possible size. c) Sketch a cross sectional drawing of the casting process with proper labeling of all the critical parts and suggest how would you modify the casting process if the cylinder part below required to be hollow instead of fully solid. r= 8 cm h = 60 cm 24 cm h = 220 cm Figure Ql
