What will be the optimum pouring time for cast iron whose mass is 100

1.	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) 14.8The question was posed to me during an interview for a job.My query is from Gating Design in portion Pattern and Mould, Principles of Gating & Risering of Casting-Forming-Welding I
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.
