Porosity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Porosity of soil = (Total Volume of Soil or Rock Sample-Volume of Solids)/Total Volume of Soil or Rock Sample
η = (V_t-V_s)/V_t
This formula uses 3 Variables

Variables Used

Porosity of soil - Porosity of soil is the ratio of the volume of voids to the volume of soil.
Total Volume of Soil or Rock Sample - (Measured in Cubic Meter) - Total Volume of Soil or Rock Sample is the combined volume of solids and pores which may contain volume of air or volume of water, or both.
Volume of Solids - (Measured in Cubic Meter) - Volume of Solids in the Samples is the measure of how much space an object takes up.

STEP 1: Convert Input(s) to Base Unit

Total Volume of Soil or Rock Sample: 50 Cubic Meter --> 50 Cubic Meter No Conversion Required
Volume of Solids: 15 Cubic Meter --> 15 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η = (V_t-V_s)/V_t --> (50-15)/50

Evaluating ... ...

η = 0.7

STEP 3: Convert Result to Output's Unit

0.7 --> No Conversion Required

FINAL ANSWER

0.7 <-- Porosity of soil

< 5 Porosity Calculators

Porosity

Go Porosity of soil = (Total Volume of Soil or Rock Sample-Volume of Solids)/Total Volume of Soil or Rock Sample

Total Volume of Soil or Rock Sample given Porosity

Go Total Volume of Soil or Rock Sample = (Volume of voids/Volume Percent of Porosity)*100

Volume of Solids given Porosity

Go Volume of Solids = (Total Volume of Soil or Rock Sample*(1-Porosity of soil))

Porosity given Bulk Pore Velocity

Go Porosity of soil = Apparent Velocity of Seepage/Bulk Pore Velocity

Porosity given Specific Yield and Specific Retention

Go Porosity of soil = Specific Yield+Specific Retention

Porosity Formula

Porosity of soil = (Total Volume of Soil or Rock Sample-Volume of Solids)/Total Volume of Soil or Rock Sample
η = (V_t-V_s)/V_t

What factors affect Porosity?

Porosity is directly dependent on the initial water content, temperature, pressure, relative humidity, air velocity, electromagnetic radiation, food material size, composition, and initial microstructure and viscoelastic properties of the biomaterial.

How to Calculate Porosity?

Porosity calculator uses Porosity of soil = (Total Volume of Soil or Rock Sample-Volume of Solids)/Total Volume of Soil or Rock Sample to calculate the Porosity of soil, Porosity or Void Fraction is a measure of the void spaces in a material and is a fraction of the volume of voids over the total volume between 0 and 1 or as a percentage between 0% and 100%. Porosity of soil is denoted by η symbol.

How to calculate Porosity using this online calculator? To use this online calculator for Porosity, enter Total Volume of Soil or Rock Sample (V_t) & Volume of Solids (V_s) and hit the calculate button. Here is how the Porosity calculation can be explained with given input values -> 0.7 = (50-15)/50.

FAQ

What is Porosity?

Porosity or Void Fraction is a measure of the void spaces in a material and is a fraction of the volume of voids over the total volume between 0 and 1 or as a percentage between 0% and 100% and is represented as η = (V_t-V_s)/V_t or Porosity of soil = (Total Volume of Soil or Rock Sample-Volume of Solids)/Total Volume of Soil or Rock Sample. Total Volume of Soil or Rock Sample is the combined volume of solids and pores which may contain volume of air or volume of water, or both & Volume of Solids in the Samples is the measure of how much space an object takes up.

How to calculate Porosity?

Porosity or Void Fraction is a measure of the void spaces in a material and is a fraction of the volume of voids over the total volume between 0 and 1 or as a percentage between 0% and 100% is calculated using Porosity of soil = (Total Volume of Soil or Rock Sample-Volume of Solids)/Total Volume of Soil or Rock Sample. To calculate Porosity, you need Total Volume of Soil or Rock Sample (V_t) & Volume of Solids (V_s). With our tool, you need to enter the respective value for Total Volume of Soil or Rock Sample & Volume of Solids and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Porosity of soil?

In this formula, Porosity of soil uses Total Volume of Soil or Rock Sample & Volume of Solids. We can use 2 other way(s) to calculate the same, which is/are as follows -

Porosity of soil = Specific Yield+Specific Retention
Porosity of soil = Apparent Velocity of Seepage/Bulk Pore Velocity
