Time Taken in Standard Specimen Testing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time = 501.28/(Permeability Number*Pressure in Casting)
t_p = 501.28/(PN*p_c)
This formula uses 3 Variables

Variables Used

Time - (Measured in Second) - Time is various stages and durations throughout the process.
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.

STEP 1: Convert Input(s) to Base Unit

Permeability Number: 4.36 Henry per Meter --> 4.36 Henry per Meter No Conversion Required
Pressure in Casting: 3.9 Kilogram-Force per Square Meter --> 38.2459349999973 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_p = 501.28/(PN*p_c) --> 501.28/(4.36*38.2459349999973)

Evaluating ... ...

t_p = 3.00613586945196

STEP 3: Convert Result to Output's Unit

3.00613586945196 Second --> No Conversion Required

FINAL ANSWER

3.00613586945196 ≈ 3.006136 Second <-- Time

(Calculation completed in 00.004 seconds)

Cross-Sectional Area of Specimen

Go Cross-Sectional Area of Specimen = (Volume of Air Flow through Specimen*Specimen Height)/(Permeability Number*Air Pressure on Wall*Time)

Air Pressure during Testing

Go Air Pressure on Wall = (Volume of Air Flow through Specimen*Specimen Height)/(Permeability Number*Cross-Sectional Area of Specimen*Time)

Time Taken during Testing

Go Time = (Volume of Air Flow through Specimen*Specimen Height)/(Permeability Number*Air Pressure on Wall*Cross-Sectional Area of Specimen)

Volume of Air Passed through Specimen

Go Volume of Air Flow through Specimen = (Permeability Number*Air Pressure on Wall*Cross-Sectional Area of Specimen*Time)/Specimen Height

Height of Specimen

Go Specimen Height = (Permeability Number*Air Pressure on Wall*Cross-Sectional Area of Specimen*Time)/Volume of Air Flow through Specimen

Permeability Number

Go Permeability Number = (Volume of Air in Casting*Height of Specimen)/(Air Pressure on Wall*Cross-Sectional Area of Specimen*Time)

Grain Fineness Number

Go Grain Fineness Number = Sum of Product of Factor and Grams/Total Mass of Sand

Ranginess Factor

Go Ranginess Factor = Modulus of Cube of Same Volume/Modulus of Casting

Pressure during Testing or Standard Specimen

Go Pressure in Casting = 501.28/(Permeability Number*Time)

Permeability Number or Standard Specimen

Go Permeability Number = 501.28/(Pressure in Casting*Time)

Time Taken in Standard Specimen Testing

Go Time = 501.28/(Permeability Number*Pressure in Casting)

Time Taken in Standard Specimen Testing Formula

Time = 501.28/(Permeability Number*Pressure in Casting)
t_p = 501.28/(PN*p_c)

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
