Pouring Time = Empirical Constant 1*sqrt(Mass of Casting)
t_pt = K₁*sqrt(W)

What is pouring time?

The time for complete filling of a mould is termed pouring time, is a very important criterion for design.Too long a pouring time requires a higher pouring temperature and too less a pouring time means turbulent flow in the mould, which makes the casting defect-prone. There is thus an optimum pouring time for any given casting.
The pouring time depends on the casting materials, complexity of the casting, section thickness and casting size. The various relations used are not theoretically obtained but established generally by the practice at various foundries and by experimenters.

What values can k take?

K1= 2.080 for thinner sections
K1= 2.670 for sections 10 to 25 mm thick
K1= 2.970 for heavier sections
