Unsupported Load for Cores Solution

STEP 0: Pre-Calculation Summary
Formula Used
Unsupported Load = Buoyant Force-Empirical constant*Core Print Area
UL = Fbuoyant-c*A
This formula uses 4 Variables
Variables Used
Unsupported Load - (Measured in Newton) - Unsupported load is the load which is not supported by anything.
Buoyant Force - (Measured in Newton) - Buoyant Force is the upward force exerted by any fluid upon a body placed in it.
Empirical constant - (Measured in Pascal) - Empirical constant is the constant used in an empirical relation. It may have some units.
Core Print Area - (Measured in Square Meter) - Core print area is the area of that part of the mould which supports the weight of core used in casting.
STEP 1: Convert Input(s) to Base Unit
Buoyant Force: 1500 Newton --> 1500 Newton No Conversion Required
Empirical constant: 350 Newton per Square Millimeter --> 350000000 Pascal (Check conversion here)
Core Print Area: 1E-06 Square Meter --> 1E-06 Square Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
UL = Fbuoyant-c*A --> 1500-350000000*1E-06
Evaluating ... ...
UL = 1150
STEP 3: Convert Result to Output's Unit
1150 Newton --> No Conversion Required
FINAL ANSWER
1150 Newton <-- Unsupported Load
(Calculation completed in 00.020 seconds)

13 Cores - Core Prints and Chaplets Calculators

Buoyant Force on Vertical Cores
Go Buoyant Force = (pi/4*(Diameter of Core Print^2-Diameter of Cylinder^2)*Height of Core Print*Density of Metal-Volume of the Core*Density of Core)*[g]
Buoyant Force on Cylindrical Cores Placed Horizontally
Go Buoyant Force = pi/4*Diameter of Cylinder^2*[g]*Cylinder Height*(Density of Metal-Density of Core)
Metallostatic Forces Acting on Moulding Flasks
Go Metallostatic Force = [g]*Density of Metal*Projected Area of the Casting in Parting plane*Head of Molten Metal
Density of Core Material
Go Density of Core = Density of Metal-Buoyant Force/(Volume of the Core*[g])
Volume of Core
Go Volume of the Core = Buoyant Force/(9.81*(Density of Metal-Density of Core))
Density of Molten Metal
Go Density of Metal = Buoyant Force/(Volume of the Core*9.81)+Density of Core
Buoyant Force on Cores
Go Buoyant Force = 9.81*Volume of the Core*(Density of Metal-Density of Core)
Chaplet Area
Go Chaplet Area = 29*(Buoyant Force-Empirical constant*Core Print Area)
Unsupported Load for Cores
Go Unsupported Load = Buoyant Force-Empirical constant*Core Print Area
Buoyant Force on Cores from Chaplet Area
Go Buoyant Force = Chaplet Area/29+Empirical constant*Core Print Area
Empirical Relation for Max. Permissible Buoyancy Force on given Core Print Area
Go Buoyant Force = Empirical constant*Core Print Area
Empirical Relation for Minimum Core Print Area
Go Core Print Area = Buoyant Force/Empirical constant
Chaplet Area from Unsupported Load
Go Chaplet Area = 29*Unsupported Load

Unsupported Load for Cores Formula

Unsupported Load = Buoyant Force-Empirical constant*Core Print Area
UL = Fbuoyant-c*A

What are chaplets?

Chaplets are metallic supports often kept inside the mould cavity to support the cores. These are of the same composition as that of the pouring metal so that the molten metal would provide enough heat to completely melt them and thus fuse with it during solidification.
In order to calculate the required chaplet area, we need to know the unsupported load.

How to Calculate Unsupported Load for Cores?

Unsupported Load for Cores calculator uses Unsupported Load = Buoyant Force-Empirical constant*Core Print Area to calculate the Unsupported Load, The Unsupported load for cores is to be defined in order to calculate the required chaplet area a. It is the load which is not supported by anything and thus has to be supported by chaplets. Unsupported Load is denoted by UL symbol.

How to calculate Unsupported Load for Cores using this online calculator? To use this online calculator for Unsupported Load for Cores, enter Buoyant Force (Fbuoyant), Empirical constant (c) & Core Print Area (A) and hit the calculate button. Here is how the Unsupported Load for Cores calculation can be explained with given input values -> 1150 = 1500-350000000*1E-06.
