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.

How to Calculate Time taken during testing?

Time taken during testing calculator uses Time in Minutes=(Volume of air flow through specimen*Height of specimen)/(Permeability Number*Air pressure*Cross-sectional area of specimen) to calculate the Time in Minutes, The Time taken during testing is time taken by air to completely pass through the sand specimen in PN testing. Time in Minutes and is denoted by t symbol.

How to calculate Time taken during testing using this online calculator? To use this online calculator for Time taken during testing, enter Volume of air flow through specimen (V), Height of specimen (h), Permeability Number (PN), Air pressure (p) and Cross-sectional area of specimen (A) and hit the calculate button. Here is how the Time taken during testing calculation can be explained with given input values -> 8.519E-6 = (0.002*0.0508)/(1*98.0664999999931*0.0020268).

FAQ

What is Time taken during testing?
The Time taken during testing is time taken by air to completely pass through the sand specimen in PN testing and is represented as t=(V*h)/(PN*p*A) or Time in Minutes=(Volume of air flow through specimen*Height of specimen)/(Permeability Number*Air pressure*Cross-sectional area of specimen). Volume of air flow through specimen is the amount of air which passes through the specimen during testing, Height of specimen is the height of specimen defined in question, Permeability Number is the rate of flow of air passing through a standard specimen under a standard pressure, Air pressure is the pressure exerted by air on the walls in which it is confined and Cross-sectional area of specimen is the area exposed when specimen is cut transversely.
How to calculate Time taken during testing?
The Time taken during testing is time taken by air to completely pass through the sand specimen in PN testing is calculated using Time in Minutes=(Volume of air flow through specimen*Height of specimen)/(Permeability Number*Air pressure*Cross-sectional area of specimen). To calculate Time taken during testing, you need Volume of air flow through specimen (V), Height of specimen (h), Permeability Number (PN), Air pressure (p) and Cross-sectional area of specimen (A). With our tool, you need to enter the respective value for Volume of air flow through specimen, Height of specimen, Permeability Number, Air pressure and Cross-sectional area of specimen and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
