Metal Head at Top Section of Sprue Solution

STEP 0: Pre-Calculation Summary

Formula Used

Metal Head at Top Section = Head at Choke Section*(Area at Choke Section/Area at Top Section)^2
h_t = h_c*(A/At)^2
This formula uses 4 Variables

Variables Used

Metal Head at Top Section - (Measured in Meter) - Metal head at top section sprue is the molten metal that accumulates at the top of the sprue, which is the vertical passage through which molten metal is poured into a mold during casting.
Head at Choke Section - (Measured in Meter) - Head at choke section sprue is the vertical height of molten metal above the narrowest point (choke) in the gating system of a casting, crucial for ensuring proper flow and filling of the mold cavity.
Area at Choke Section - (Measured in Square Meter) - Area at choke section of sprue is the area at that part of sprue where it runs full of metal.
Area at Top Section - (Measured in Square Meter) - Area at top section is the surface area at the uppermost part of a component or structure.

STEP 1: Convert Input(s) to Base Unit

Head at Choke Section: 7 Centimeter --> 0.07 Meter (Check conversion here)
Area at Choke Section: 16.73 Square Centimeter --> 0.001673 Square Meter (Check conversion here)
Area at Top Section: 14 Square Centimeter --> 0.0014 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_t = h_c*(A/At)^2 --> 0.07*(0.001673/0.0014)^2

Evaluating ... ...

h_t = 0.09996175

STEP 3: Convert Result to Output's Unit

0.09996175 Meter -->9.996175 Centimeter (Check conversion here)

FINAL ANSWER

9.996175 Centimeter <-- Metal Head at Top Section

What is sprue?

Sprue is the channel through which the molten metal is brought into the parting plane, where it enters the runners and gates to ultimately reach the mould cavity. The molten metal when moving from top of the cope to the parting plane gains in velocity, and as a consequence, requires a smaller area of cross section for the same amount of metal to flow at the top. If the sprue were to be straight-cylindrical then the metal
flow would not be full at the bottom, but some low-pressure area would be created around the metal in the sprue.

How to Calculate Metal Head at Top Section of Sprue?

Metal Head at Top Section of Sprue calculator uses Metal Head at Top Section = Head at Choke Section*(Area at Choke Section/Area at Top Section)^2 to calculate the Metal Head at Top Section, Metal Head at Top Section of Sprue the vertical distance between the surface of the molten metal in the pouring basin or ladle and the top section of the sprue. It is a critical parameter that determines the pressure and flow rate of the molten metal into the sprue and subsequently into the mold cavity. Metal Head at Top Section is denoted by h_t symbol.

How to calculate Metal Head at Top Section of Sprue using this online calculator? To use this online calculator for Metal Head at Top Section of Sprue, enter Head at Choke Section (h_c), Area at Choke Section (A) & Area at Top Section (At) and hit the calculate button. Here is how the Metal Head at Top Section of Sprue calculation can be explained with given input values -> 999.6175 = 0.07*(0.001673/0.0014)^2.
