Question

Porosity and void ratio are related by:

(a) e = ^n⁄(1-n)

(b) n = ^e⁄(1-e)

(c) 1-e = n

(d) ^(1+n)⁄n = e-1

I have been asked this question by my school teacher while I was bunking the class.

This question is from Geotechnical Engineering topic in portion Other Major Topics in Civil Engineering of Basic Civil Engineering

Answer 1

Right answer is (a) e = ^n⁄(1-n)

For explanation I would say: Void ratio is e and porosity is n. Another relationship between the two is

n = ^e⁄(1+e)
