Effective Metal Head for Bottom Gate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effective Metal Head for Bottom Gate = Height of Sprue-Total Height of Mould Cavity/2
H_E = h-c/2
This formula uses 3 Variables

Variables Used

Effective Metal Head for Bottom Gate - (Measured in Meter) - Effective metal head for Bottom gate depends on the casting dimensions and the type of gating used.
Height of Sprue - (Measured in Meter) - Height of Sprue is the height that is specified of sprue passage only, used in mould during casting.
Total Height of Mould Cavity - (Measured in Meter) - Total Height of Mould Cavity is the height of the mould in cavity and denoted by c symbol.

STEP 1: Convert Input(s) to Base Unit

Height of Sprue: 9 Centimeter --> 0.09 Meter (Check conversion here)
Total Height of Mould Cavity: 4.5 Centimeter --> 0.045 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_E = h-c/2 --> 0.09-0.045/2

Evaluating ... ...

H_E = 0.0675

< 6 Choke Area Calculators

Density of Molten Metal using Bernoulli's Equation

Go Density of Metal = Casting Mass/(Area at Choke Section of Sprue*Pouring Time of Mould*Efficiency Factor of Gating System*sqrt(2*[g]*Effective Metal Head))

Pouring Time using Bernoulli's Equation

Go Pouring Time of Mould = Casting Mass/(Density of Metal*Area at Choke Section of Sprue*Efficiency Factor of Gating System*sqrt(2*[g]*Effective Metal Head))

Choke Area using Bernoulli's Equation

Go Area at Choke Section of Sprue = Casting Mass/(Density of Metal*Pouring Time of Mould*Efficiency Factor of Gating System*sqrt(2*[g]*Effective Metal Head))

Casting Mass using Bernoulli's Equation

Go Casting Mass = Area at Choke Section of Sprue*Density of Metal*Pouring Time of Mould*Efficiency Factor of Gating System*sqrt(2*[g]*Effective Metal Head)

Effective Metal Head for Parting Gate

Go Effective Metal Head for parting Gate = Height of Sprue-(Height of Mould Cavity in Cope^2)/(2*Total Height of Mould Cavity)

Effective Metal Head for Bottom Gate

Go Effective Metal Head for Bottom Gate = Height of Sprue-Total Height of Mould Cavity/2

Effective Metal Head for Bottom Gate Formula

Effective Metal Head for Bottom Gate = Height of Sprue-Total Height of Mould Cavity/2
H_E = h-c/2

What is Effective metal head?

Effective metal head is the actual head of metal available at the gate of mould cavity. It is the head which will get converted to velocity of molten metal available for filling the mould cavity. It is usually different for many different gating systems. For top gating system it is same as sprue height.
