Percent pore space can be calculated by using of which formula
A. $$\% {\text{PS}} = {\text{100}} - \left( {\frac{{{{\text{D}}_{\text{p}}}}}{{{{\text{D}}_{\text{b}}}}} \times 100} \right)$$
B. $$\% {\text{PS}} = {\text{100}} - \left( {\frac{{{{\text{D}}_{\text{b}}}}}{{{{\text{D}}_{\text{p}}}}} \times 100} \right)$$
C. $$\% {\text{PS}} = {\text{1}} - \left( {\frac{{{{\text{D}}_{\text{p}}}}}{{{{\text{D}}_{\text{b}}}}} \times 100} \right)$$
D. $$\% {\text{PS}} = \left( {\frac{{{{\text{D}}_{\text{p}}}}}{{{{\text{D}}_{\text{P}}}}} \times 100} \right)$$
Answer: Option B
Solution (By Examveda Team)
Percent pore space is defined by the porosity of a material possessing free space between the mineral grains expressed in percentage. It is proposed by Rebollo et al., 1996.It depends on the size and sorting of the particles as a cubic or hexagonal package.
$$\% {\text{PS}} = 100 - \left( {\frac{{{{\text{D}}_{\text{b}}}}}{{{{\text{D}}_{\text{p}}}}} \times 100} \right)$$
