Density of Molten Metal using Bernoulli's Equation

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

Pouring Time using Bernoulli's Equation

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

Choke Area using Bernoulli's Equation

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

Casting Mass using Bernoulli's Equation

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

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.

How to Calculate Effective Metal Head for Bottom Gate?

Effective Metal Head for Bottom Gate calculator uses Effective Metal Head For Bottom Gate = Height of Sprue-Total Height of Mould Cavity/2 to calculate the Effective Metal Head For Bottom Gate, Effective Metal Head for Bottom Gate is the vertical distance between the surface of the molten metal in the pouring basin or sprue and the gate through which the metal enters the mold cavity and calculated as the difference in height between the pouring basin or sprue and the gate, taking into account any losses due to friction and turbulence in the gating system. Effective Metal Head For Bottom Gate is denoted by H_b symbol.

How to calculate Effective Metal Head for Bottom Gate using this online calculator? To use this online calculator for Effective Metal Head for Bottom Gate, enter Height of Sprue (h) & Total Height of Mould Cavity (c) and hit the calculate button. Here is how the Effective Metal Head for Bottom Gate calculation can be explained with given input values -> 675 = 0.09-0.045/2.
