Question

Give the name of the methods and porosity determination​

Answer 1

Explanation:

The four techniques used to measure porosity are examined: mercury porosimetry, helium pycnometry, image analysis and water absorption. Helium pycnometry allows determination of both open and closed porosity with greatly contained error.

Answer 2

Answer:Method                                        Porosity Type

Grain Determination by Immersion  -      Total Porosity, ϕt

Grain Determination by Boyles Law  -      Effective Porosity, ϕe

Washburn-Bunting (Mercury Injection)  -      Effective Porosity, ϕe

Resaturation                                          -      Effective Porosity, ϕe-
