first of all sorry for such long delay 🙁 Anyway I think the data given is incomplete in this question that’s why now I am giving u only formulas: a) For Latent heat calculate “B” from the formula as: t = B * [(Casting modulus)^n] where, t = Solidification Time (given) B = Mold Constant n = 1.5 to 2 (Take 2 if not given) Then after finding “B” calculate Latent heat as:

B = {[(ρm*L)/(Tm-T0)]^2}*{[3.1428/(4*K*ρ*C)]}*{1+[(Cm*ΔTs)/L]}

Where, Tm = melting or freezing temperature of the liquid To = initial temperature of the mold ΔTs = Tpour − Tm = superheat L = latent heat of fusion K = thermal conductivity of the mold ρ = density of the mold C = specific heat of the mold ρm = density of the metal Cm = specific heat of the metal

b) For Fluidity of Short Freezing Range Alloys the formula is, Fluidity Distance, Lf = V * t

where, V = flow velocity t = solidification time

If the data is not given in the problem then take any appropriate material & take respective data & put it in formula… 🙂

Well I don’t think this kind of question can be asked in GATE; if asked then it should be deserve 10 marks lol … Hope this could satisfied you a bit…. … .. .
