The image above represents pouring time for thin-walled casting 450kg in mass.

To compute for pouring time thin-walled casting 450kg in mass, two essential parameters are **Co-efficient used to Account for Wall Thickness (S)** and **Mass of Casting with Gates and Risers (G).**

The formula for calculating pouring time for thin-walled casting 450kg in mass:

t = S√(G)

Where:

t = Pouring Time for Thin-Walled Casting 450kg in Mass

S = Co-efficient used to Account for Wall Thickness

G = Mass of Casting with Gates and Risers

Let’s solve an example;

Find the pouring time for thin-walled casting 450kg in mass when the co-efficient used to account for wall thickness is 20 and the mass of casting with gates and risers is 32.

This implies that;

S = Co-efficient used to Account for Wall Thickness = 20

G = Mass of Casting with Gates and Risers = 32

t = S√(G)

t = 20 x √(32)

t = 20 x 5.65

t = **113.13**

Therefore, the **pouring time for thin-walled casting 450kg in mass **is **113.13 s.**

**Calculating the Co-efficient used to Account for Wall Thickness when the Pouring Time for Thin-Walled Casting 450kg in Mass and the Mass of Casting with Gates and Risers is Given.**

S = ^{t} / _{√(G)}

Where;

S = Co-efficient used to Account for Wall Thickness

t = Pouring Time for Thin-Walled Casting 450kg in Mass

G = Mass of Casting with Gates and Risers

Let’s solve an example;

Find the co-efficient used to account for wall thickness when the pouring time for thin-walled casting 450kg in mass is 30 and the mass of casting with gates and risers is 25.

This implies that;

t = Pouring Time for Thin-Walled Casting 450kg in Mass = 30

G = Mass of Casting with Gates and Risers = 25

S = ^{t} / _{√(G)}

S = ^{30} / _{√25}

S = ^{30} / _{5}

S = 6

Therefore, the **co-efficient used to account for wall thickness **is **6.**
