What will be the optimum pouring time for cast iron whose mass is 100 kg and a thickness of 25 mm? Fluidity of iron is 32 inches?(a) 24.98(b) 18.2(c) 31.32(d) 14.8 |

Answer» The correct option is (a) 24.98 For explanation I would say: Pouring time(t) = K[ 1.41 + T/14.59]√W sec. where K = Fluidity of iron in inches/40 Pouring time(t) = 32/40[ 1.41 + 25/14.59]√100 = 24.988 sec. |
