Extracted text: In casting experiments performed during a certain alloy and type of sand mould it took 155 second for a cube shaped casting to solidify. The cube was 50 mm on a side. (i) Determine the value of the mould constant in Chvorinov's Rule. (ii) If the same alloy and mould type were used, find the total solidification time for cylindrical casting in which the diameter D = 30 mm and length L = 50 mm. %3D
