Which of the following relations is given by chvorinov for the solidification time of a casting?(a) ts = k(V/SA)^2(b) ts = k(V/SA)(c) ts = k(V*SA)^2(d) ts = k(V/SA)^3 |

Answer» The correct option is (a) ts = k(V/SA)^2 For explanation I would say: Chvorinov scientist has shown that the solidification time of a casting is directly proportional to the square of the ratio of volume-to-surface area of the casting and the constant of proportionality is known as mould constant. His relation is given by: ts = k(V/SA)^2, where ts = solidification time, V = volume, SA = surface area, k = mould constant. |
