The image above represents total latent heat. To calculate the total latent heat, three essential parameters are needed, and these parameters are the Density of Solidifying Metal (ρ’), Volume of Casting (V), and Latent Heat of Fusion (Hf).
The formula for calculating the total latent heat:
Q = ρ’VHf
Where:
Q = Total Latent Heat
ρ = Density of Solidifying Metal
V = Volume of Casting
Hf = Latent Heat of Fusion
Let’s solve an example;
Find the total latent heat when the density of solidifying metal is 12, the volume of casting is 14 and the latent heat of fusion is 10.
This implies that;
ρ = Density of Solidifying Metal = 12
V = Volume of Casting = 14
Hf = Latent Heat of Fusion = 10
Q = ρ’VHf
That is, Q = (12)(14)(10)
Q = 1680
Therefore, the total latent heat is 1680 J/Kg.
Calculating the Density of Solidifying Metal when the Total Latent Heat, the Volume of Casting and the Latent Heat of Fusion are Given
ρ = Q / VHf
Where;
ρ = Density of Solidifying Metal
Q = Total Latent Heat
V = Volume of Casting
Hf = Latent Heat of Fusion
Let’s solve an example;
Find the density of solidifying metal when the total latent heat is 20, the volume of casting is 4 and the latent heat of fusion is 2.
This implies that;
Q = Total Latent Heat = 20
V = Volume of Casting = 4
Hf = Latent Heat of Fusion = 2
ρ = Q / VHf
So, ρ = 20 / (4)(2)
ρ = 20 / 8
ρ = 2.5
Therefore, the density of solidifying metal is 2.5

Calculating the Volume of Casting when the Total Latent Heat, the Density of Solidifying Metal and the Latent Heat of Fusion are Given
V = Q / ρHf
Where;
V = Volume of Casting
Q = Total Latent Heat
ρ = Density of Solidifying Metal
Hf = Latent Heat of Fusion
Let’s solve an example;
Find the volume of casting when the total latent heat is 18, the density of solidifying metal is 3 and the latent heat of fusion is 3.
This implies that;
Q = Total Latent Heat = 18
ρ = Density of Solidifying Metal = 3
Hf = Latent Heat of Fusion = 3
V = Q / ρHf
Then, V = 18 / (3)(3)
V = 18 / 9
V = 2
Therefore, the volume of casting is 2.

Hf = Latent Heat of Fusion
Q = Total Latent Heat
ρ = Density of Solidifying Metal
V = Volume of Casting
Let’s solve an example;
Find the latent heat of fusion when the total latent heat is 44, the density of solidifying metal is 11 and the volume of casting is 2.
This implies that;
Q = Total Latent Heat = 44
ρ = Density of Solidifying Metal = 11
V = Volume of Casting = 2
Hf = Q / ρV
Hf = 44 / (11)(2)
So, Hf = 44 / 22
Hf = 2
Therefore, the latent heat of fusion is 2.
