The image above represents relative freezing time. To calculate relative freezing time, four essential parameters are needed and these parameters are Constant (L), Constant (C), Volume of Riser\/Volume of Casting (y)\u00a0<\/strong>and\u00a0Relative Contraction of Freezing (B).<\/strong><\/p>\n

The formula for calculating relative freezing time:<\/p>\n

x =\u00a0L<\/sup>\u00a0\/\u00a0y – B<\/sub> + C<\/p>\n

Where:<\/p>\n

x = Relative Freezing Time
\ny = Volume of Riser \/ Volume of Casting
\nB = Relative Contraction on Freezing
\nC = Constant
\nL = Constant<\/p>\n

Let’s solve an example;
\nFind the relative freezing time when the volume of riser\/volume of casting is 26, the relative contraction on freezing is 21, the constant is 8 and the constant is 11.<\/p>\n

This implies that;<\/p>\n

y = Volume of Riser \/ Volume of Casting = 26
\nB = Relative Contraction on Freezing = 21
\nC = Constant = 11
\nL = Constant = 8<\/p>\n

x =\u00a0L<\/sup>\u00a0\/\u00a0y – B<\/sub> + C
\nx =\u00a08<\/sup>\u00a0\/\u00a026 – 21<\/sub>\u00a0+ 11
\nSo, x = 8<\/sup>\u00a0\/\u00a05<\/sub> + 11
\nx = 1.6 + 11
\nx =\u00a012.6<\/b><\/p>\n

Therefore, the\u00a0relative freezing time\u00a0<\/strong>is\u00a012.6 s.<\/strong><\/p>\n

Calculating the Constant (L) when the Relative Freezing Time, Constant (C), the Volume of riser\/Volume of Casting and the Relative Contraction on Freezing are Given.<\/strong><\/h3>\n

L = x (y – B) – C<\/p>\n

Where;<\/p>\n

L = Constant
\nx = Relative Freezing Time
\ny = Volume of riser \/ Volume of Casting
\nB = Relative Contraction on Freezing
\nC = Constant<\/p>\n

Let’s solve an example;
\nFind the Constant when the relative freezing time is 24, the volume of riser \/ volume of casting is 14, the relative contraction on freezing is 8 and the constant is 10.<\/p>\n

This implies that;<\/p>\n

x = Relative Freezing Time = 24
\ny = Volume of riser \/ Volume of Casting = 14
\nB = Relative Contraction on Freezing = 8
\nC = Constant = 10<\/p>\n

L = x (y -B) – C
\nL = 24 (14 – 8) – 10
\nThen, L = 24 (6) – 10
\nL = 144 – 10
\nL = 134<\/p>\n

Therefore, the\u00a0constant\u00a0<\/strong>is\u00a0134.<\/strong><\/p>\n

Calculating the Constant (C) when the Relative Freezing Time, the Constant (L), the Volume of Riser \/ Volume of Casting and the Relative Contraction on Freezing are Given<\/strong><\/h3>\n

C = x (y – B) – L<\/p>\n

Where;<\/p>\n

C = Constant
\nx = Relative Freezing Time
\ny = Volume of Riser \/ Volume of Casting
\nB = Relative Contraction on Freezing
\nL = Constant<\/p>\n

Let’s solve an example;
\nFind the constant when the relative freezing time is 5, the volume of riser \/ volume of casting is 10, the relative contraction on freezing is 2 and the constant is 4.<\/p>\n

This implies that;<\/p>\n

x = Relative Freezing Time = 5
\ny = Volume of Riser \/ Volume of Casting = 10
\nB = Relative Contraction on Freezing = 2
\nL = Constant = 4<\/p>\n

C = x (y – B ) – L
\nC = 5 (10 – 2) – 4
\nThen, C = 5 (8) – 4
\nC = 40 – 4
\nC = 36<\/p>\n

Therefore, the\u00a0constant\u00a0<\/strong>is\u00a036.<\/strong><\/p>\n

Calculating the Volume of Riser \/ Volume of Casting when the Relative Freezing Time, the Constant (L), the Constant (C) and the Relative Contraction on Freezing are Given<\/strong><\/h3>\n

y = L + C<\/sup> \/ x<\/sub> + B<\/p>\n

Where;<\/p>\n

y = Volume of Riser \/ Volume of Casting
\nL = Constant
\nC = Constant
\nx = Relative Freezing Time
\nB = Relative Contraction on Freezing<\/p>\n

Let’s solve an example;
\nGiven that the constant is 12, the relative freezing time is 6, the constant is 24 and the relative contraction on freezing is 3. Find the Volume of riser \/ Volume of casting?<\/p>\n

This implies that;<\/p>\n

L = Constant = 12
\nC = Constant = 24
\nx = Relative Freezing Time = 6
\nB = Relative Contraction on Freezing = 3<\/p>\n

y = L + C<\/sup> \/ x<\/sub> + B
\ny = 12 + 24<\/sup> \/ 6<\/sub> + 3
\nSo, y = 36<\/sup> \/ 6<\/sub> + 3
\ny = 6 + 3
\ny = 9<\/p>\n

Therefore, the\u00a0volume of riser \/ volume of casting\u00a0<\/strong>is\u00a09.<\/strong><\/p>\n

Calculating the Relative Contraction on Freezing when the Relative Freezing Time, the Constant (L), the Constant (C) and the Volume of Riser \/ Volume of Casting are Given<\/strong><\/h3>\n

B = y – L + C<\/sup> \/ x<\/sub><\/p>\n

Where;<\/p>\n

B = Relative Contraction on Freezing
\ny = Volume of Riser \/ Volume of Casting
\nL = Constant
\nC = Constant
\nx = Relative Freezing Time<\/p>\n

Let’s solve an example;
\nFind the relative contraction on freezing when the volume of riser \/ volume of casting is 32, the constant is 20, the constant is 12 and the relative freezing time is 8.<\/p>\n

This implies that;<\/p>\n

y = Volume of Riser \/ Volume of Casting = 32
\nL = Constant = 20
\nC = Constant = 12
\nx = Relative Freezing Time = 8<\/p>\n

B = y – L + C<\/sup> \/ x<\/sub>
\nB = 32 – 20 + 12<\/sup> \/ 8<\/sub>
\nThat is, B = 32 – 32<\/sup> \/ 8<\/sub>
\nB = 32 – 4
\nB = 28<\/p>\n

Therefore, the\u00a0relative contraction on freezing\u00a0<\/strong>is\u00a028.<\/strong><\/p>\n
