STEP 0: Pre-Calculation Summary
Formula Used
Permeability Number = 501.28/(Pressure in Casting*Time)
PN = 501.28/(pc*tp)
This formula uses 3 Variables
Variables Used
Permeability Number - (Measured in Henry per Meter) - Permeability Number is the rate of flow of air passing through a standard specimen under a standard pressure.
Pressure in Casting - (Measured in Pascal) - Pressure in Casting is the force per unit area.
Time - (Measured in Second) - Time is the fundamental dimension of measurement.
STEP 1: Convert Input(s) to Base Unit
Pressure in Casting: 3.9 Kilogram-Force per Square Meter --> 38.2459349999973 Pascal (Check conversion here)
Time: 3 Second --> 3 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
PN = 501.28/(pc*tp) --> 501.28/(38.2459349999973*3)
Evaluating ... ...

11 Permeability Number Calculators

Cross-Sectional Area of Specimen
Go Cross-sectional area of specimen = (Volume of Air Flow through Specimen*Specimen Height)/(Permeability Number*Air pressure on wall*Time)
Air Pressure during Testing
Go Air pressure on wall = (Volume of Air Flow through Specimen*Specimen Height)/(Permeability Number*Cross-sectional area of specimen*Time)
Time Taken during Testing
Go Time = (Volume of Air Flow through Specimen*Specimen Height)/(Permeability Number*Air pressure on wall*Cross-sectional area of specimen)
Volume of Air Passed through Specimen
Go Volume of Air Flow through Specimen = (Permeability Number*Air pressure on wall*Cross-sectional area of specimen*Time)/Specimen Height
Height of Specimen
Go Specimen Height = (Permeability Number*Air pressure on wall*Cross-sectional area of specimen*Time)/Volume of Air Flow through Specimen
Permeability Number
Go Permeability Number = (Volume of air*Height of Specimen)/(Air pressure on wall*Cross-sectional area of specimen*Time)
Grain Fineness Number
Go Grain Fineness Number = Sum of Product of Factor and Grams/Total Mass of Sand
Pressure during Testing or Standard Specimen
Go Pressure in Casting = 501.28/(Permeability Number*Time)
Permeability Number or Standard Specimen
Go Permeability Number = 501.28/(Pressure in Casting*Time)
Time Taken in Standard Specimen Testing
Go Time = 501.28/(Permeability Number*Pressure in Casting)
Ranginess Factor
Go Ranginess Factor = Modulus of Cube/Modulus of Casting

Permeability Number or Standard Specimen Formula

Permeability Number = 501.28/(Pressure in Casting*Time)

What is permeability number?

The Permeability Number the rate of flow of air passing through a standard specimen under a standard pressure.
The standard permeability test is to measure time taken by a 2000 cub cm of air at a pressure typically of 980 Pa (10 g/cm2), to pass through a standard sand specimen confined in a specimen tube. The standard specimen size is 50.8 mm in diameter and a length of 50.8 mm.
