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
ht = hc*(A/At)^2
This formula uses 4 Variables
Variables Used
Metal Head at Top Section - (Measured in Meter) - Metal head at top section sprue can be defined as the potential head of molten metal at top section of sprue.
Head at Choke Section - (Measured in Meter) - Head at choke section sprue is the metallostatic head available at a certain portion of sprue where it is full of metal.
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 area at the top section.
STEP 1: Convert Input(s) to Base Unit
Head at Choke Section: 7 Centimeter --> 0.07 Meter (Check conversion here)
Area at Choke Section: 12 Square Centimeter --> 0.0012 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
ht = hc*(A/At)^2 --> 0.07*(0.0012/0.0014)^2
Evaluating ... ...
ht = 0.0514285714285714
STEP 3: Convert Result to Output's Unit
0.0514285714285714 Meter -->5.14285714285714 Centimeter (Check conversion here)
FINAL ANSWER
5.14285714285714 5.142857 Centimeter <-- Metal Head at Top Section
(Calculation completed in 00.004 seconds)

Metal Head at Top Section of Sprue Formula

Metal Head at Top Section = Head at Choke Section*(Area at Choke Section/Area at Top Section)^2
ht = hc*(A/At)^2

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?
