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 Height of specimen?

Height of specimen calculator uses Height of specimen=(Permeability Number*Air pressure*Cross-sectional area of specimen*Time in Minutes)/Volume of air flow through specimen to calculate the Height of specimen, The Height of specimen formula is defined as the height of sand specimen as described in standard testing. It taken as 5.08 cm. Height of specimen and is denoted by h symbol.

How to calculate Height of specimen using this online calculator? To use this online calculator for Height of specimen, enter Permeability Number (PN), Air pressure (p), Cross-sectional area of specimen (A), Time in Minutes (t) and Volume of air flow through specimen (V) and hit the calculate button. Here is how the Height of specimen calculation can be explained with given input values -> 1.193E+7 = (1*98.0664999999931*0.0020268*1200)/0.002.

FAQ

What is Height of specimen?
The Height of specimen formula is defined as the height of sand specimen as described in standard testing. It taken as 5.08 cm and is represented as h=(PN*p*A*t)/V or Height of specimen=(Permeability Number*Air pressure*Cross-sectional area of specimen*Time in Minutes)/Volume of air flow through specimen. 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, Cross-sectional area of specimen is the area exposed when specimen is cut transversely, Time in Minutes - To convert time to minutes, multiply the time by 1440, which is the number of minutes in a day (24*60) and Volume of air flow through specimen is the amount of air which passes through the specimen during testing.
How to calculate Height of specimen?
The Height of specimen formula is defined as the height of sand specimen as described in standard testing. It taken as 5.08 cm is calculated using Height of specimen=(Permeability Number*Air pressure*Cross-sectional area of specimen*Time in Minutes)/Volume of air flow through specimen. To calculate Height of specimen, you need Permeability Number (PN), Air pressure (p), Cross-sectional area of specimen (A), Time in Minutes (t) and Volume of air flow through specimen (V). With our tool, you need to enter the respective value for Permeability Number, Air pressure, Cross-sectional area of specimen, Time in Minutes and Volume of air flow through specimen and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
