Area at Choke Section of Sprue Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area of Sprue in Choke Section = Area at Top Section*sqrt(Metal Head at Top Section/Head at Choke Section)
A = At*sqrt(h_t/h_c)
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Area of Sprue in Choke Section - (Measured in Square Meter) - Area of Sprue in Choke Section 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.
Metal Head at Top Section - (Measured in Meter) - Metal Head at Top Section is the length of 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 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.

STEP 1: Convert Input(s) to Base Unit

Area at Top Section: 14 Square Centimeter --> 0.0014 Square Meter (Check conversion here)
Metal Head at Top Section: 10 Centimeter --> 0.1 Meter (Check conversion here)
Head at Choke Section: 7 Centimeter --> 0.07 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = At*sqrt(h_t/h_c) --> 0.0014*sqrt(0.1/0.07)

Evaluating ... ...

A = 0.00167332005306815

STEP 3: Convert Result to Output's Unit

0.00167332005306815 Square Meter -->16.7332005306815 Square Centimeter (Check conversion here)

FINAL ANSWER

16.7332005306815 ≈ 16.7332 Square Centimeter <-- Area of Sprue in Choke 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 Area at Choke Section of Sprue?

Area at Choke Section of Sprue calculator uses Area of Sprue in Choke Section = Area at Top Section*sqrt(Metal Head at Top Section/Head at Choke Section) to calculate the Area of Sprue in Choke Section, The Area at choke section of sprue is the area at that part of sprue where it runs full of metal. It can be taken conveniently anywhere on the sprue. Area of Sprue in Choke Section is denoted by A symbol.
