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=(Total Volume of Soil or Rock Sample-Volume of Solids)/Total Volume of Soil or Rock Sample to calculate the 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%. Porosity and 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) and Volume of Solids (V_s) and hit the calculate button. Here is how the Porosity calculation can be explained with given input values -> -0.5 = (10-15)/10.

FAQ

What is Porosity?

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=(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) and Volume of Solids (V_s). With our tool, you need to enter the respective value for Total Volume of Soil or Rock Sample and 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?

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

Porosity=(Volume of voids/Volume of soil)
Porosity=(Void ratio/(1+Void ratio))
