Time Taken during Testing Solution

Follow our step by step solution on how to calculate Time Taken during Testing?

FIRST Step Consider the formula

t p = \frac{V \cdot H sp}{PN \cdot ρ \cdot A}

Next Step Substitute values of Variables

∴

t p = \frac{0.002m³ \cdot 5m}{4.36H/m \cdot 0.0385kgf/m² \cdot 0.002m²}

Next Step Convert Units

∴

t p = \frac{0.002m³ \cdot 5m}{4.36H/m \cdot 0.3776Pa \cdot 0.002m²}

Next Step Prepare to Evaluate

∴

t p = \frac{0.002 \cdot 5}{4.36 \cdot 0.3776 \cdot 0.002}

Next Step Evaluate

∴

t p = 2.99694213009984s

LAST Step Rounding Answer

∴

t p = 2.9969s

How to Evaluate Time Taken during Testing?

Time Taken during Testing evaluator uses Time = (Volume of Air Flow Through Specimen*Specimen Height)/(Permeability Number*Air Pressure on Wall*Cross-Sectional Area of Specimen) to evaluate the Time, The Time taken during testing is time taken by air to completely pass through the sand specimen in PN testing. Time is denoted by t_p symbol.

How to evaluate Time Taken during Testing using this online evaluator? To use this online evaluator for Time Taken during Testing, enter Volume of Air Flow Through Specimen (V), Specimen Height (H_sp), Permeability Number (PN), Air Pressure on Wall (ρ) & Cross-Sectional Area of Specimen (A) and hit the calculate button.

FAQs on Time Taken during Testing

What is the formula to find Time Taken during Testing?

The formula of Time Taken during Testing is expressed as Time = (Volume of Air Flow Through Specimen*Specimen Height)/(Permeability Number*Air Pressure on Wall*Cross-Sectional Area of Specimen). Here is an example- 2.996942 = (0.002*5)/(4.36*0.377556024999973*0.002027).

How to calculate Time Taken during Testing?

With Volume of Air Flow Through Specimen (V), Specimen Height (H_sp), Permeability Number (PN), Air Pressure on Wall (ρ) & Cross-Sectional Area of Specimen (A) we can find Time Taken during Testing using the formula - Time = (Volume of Air Flow Through Specimen*Specimen Height)/(Permeability Number*Air Pressure on Wall*Cross-Sectional Area of Specimen).
