STEP 1: Convert Input(s) to Base Unit

Permeability Number: 4.36 Henry per Meter --> 4.36 Henry per Meter No Conversion Required
Air Pressure on Wall: 0.0385 Kilogram-Force per Square Meter --> 0.377556024999973 Pascal (Check conversion here)
Cross-Sectional Area of Specimen: 0.002027 Square Meter --> 0.002027 Square Meter No Conversion Required
Time: 3 Second --> 3 Second No Conversion Required
Volume of Air Flow Through Specimen: 0.002 Cubic Meter --> 0.002 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_sp = (PN*ρ*A*t_p)/V --> (4.36*0.377556024999973*0.002027*3)/0.002

Evaluating ... ...

H_sp = 5.00510164989414

STEP 3: Convert Result to Output's Unit

5.00510164989414 Meter --> No Conversion Required

FINAL ANSWER

5.00510164989414 ≈ 5.005102 Meter <-- Specimen Height

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 Specimen Height = (Permeability Number*Air Pressure on Wall*Cross-Sectional Area of Specimen*Time)/Volume of Air Flow Through Specimen to calculate the Specimen Height, The Height of Specimen in a casting process is determined by the product of the permeability number, pressure exerted, cross-sectional area, time, and the reciprocal of the volume of air. Specimen Height is denoted by H_sp 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 on Wall (ρ), Cross-Sectional Area of Specimen (A), Time (t_p) & 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 -> 5.005102 = (4.36*0.377556024999973*0.002027*3)/0.002.
