Solution to Exercise 2
2) Show that n = e/(1 + e), where n is porosity and e is the void ratio.
Porosity is defined by Equation 6 of this book. And, when the effective porosity equals the interconnected porosity then VI = Vv.
![]() |
Void Ratio is defined by Equation 7 of this book.
![]() |
The total volume is the sum of the solid and the void volume.
VT = VV + VS |
Using the three relationships we can show:
![]() |
![]() |
![]() |
![]() |
This matches Equation 8 of this book.
