Empirical Relation for Minimum Core Print Area Solution

STEP 0: Pre-Calculation Summary
Formula Used
Core Print Area = Buoyant Force/Empirical constant
A = Fbuoyant/c
This formula uses 3 Variables
Variables Used
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.
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.
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)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
A = Fbuoyant/c --> 1500/350000000
Evaluating ... ...
A = 4.28571428571429E-06

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

Empirical Relation for Minimum Core Print Area Formula

Core Print Area = Buoyant Force/Empirical constant
A = Fbuoyant/c

What to consider while designing core prints for molding?

Core print area is the area of that part of the mould which supports the weight of core used in casting. The design of core prints is such as to take care of the weight of the core before pouring and the upward metallostatic pressure of the molten metal after pouring. The core prints should also ensure that the core is not shifted during the entry of the metal into the mould cavity.
