The page shows the True porosity formula to calculate the bulk density and porosity relationship of any material. It can be computed based on the apparent solid specific gravity and true specific gravity. According to the given Porosity equation bulk density, just divide the true specific gravity from apparent solid specific gravity. Subtract the obtained value from 1. Now multiply the resultant value with 100 to calculate the value in percentage.
You can also use our online calculator developed as per the true porosity formula mentioned above to cross-check your manually computed true porosity percentage in few fraction of seconds.
