Permeability Number or Standard Specimen Solution

STEP 0: Pre-Calculation Summary

Formula Used

Permeability Number = 501.28/(Pressure in Casting*Time)
PN = 501.28/(p_c*t_p)
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 applied to the molten metal during the casting process, which can affect the flow, filling, and solidification of the material.
Time - (Measured in Second) - Time is various stages and durations throughout the casting process.

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/(p_c*t_p) --> 501.28/(38.2459349999973*3)

Evaluating ... ...

PN = 4.36891746360352

STEP 3: Convert Result to Output's Unit

4.36891746360352 Henry per Meter --> No Conversion Required

FINAL ANSWER

4.36891746360352 ≈ 4.368917 Henry per Meter <-- Permeability Number

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.
