12 Permeability Number Calculators

Cross-Sectional Area of Specimen
Go Cross-sectional area of specimen = (Volume of Air Flow through Specimen*Height of Specimen)/(Permeability Number*Air pressure*Time)
Air Pressure during Testing
Go Air pressure = (Volume of Air Flow through Specimen*Height of Specimen)/(Permeability Number*Cross-sectional area of specimen*Time)
Time Taken during Testing
Go Time = (Volume of Air Flow through Specimen*Height of Specimen)/(Permeability Number*Air pressure*Cross-sectional area of specimen)
Volume of Air Passed through Specimen
Go Volume of Air Flow through Specimen = (Permeability Number*Air pressure*Cross-sectional area of specimen*Time)/Height of Specimen
Height of Specimen
Go Height of Specimen = (Permeability Number*Air pressure*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*Cross-sectional area of specimen*Time)
Pouring Temperature from Fluidity Spiral Length
Go Pouring temperature = (389.6+Fluidity spiral length-37.846*Coefficient of Fluctuation of Flywheel Speed)/0.228
Ranginess Factor
Go Ranginess Factor = Modulus of Cube of same Volume as Casting/Modulus of Casting
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 = 501.28/(Permeability Number*Time)
Permeability Number or Standard Specimen
Go Permeability Number = 501.28/(Pressure*Time)
Time Taken in Standard Specimen Testing
Go Time = 501.28/(Permeability Number*Pressure)

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.
