The degree of disturbance of the sample collected by the sampler is expressed by a term called the "area ratio". If the outer diameter and inner diameter of the sampler are Do and Di respectively, the area ratio is given by
1
\(\frac{{D_0^2 - D_i^2}}{{D_i^2}}\)
2
\(\frac{{D_i^2 - D_0^2}}{{D_i^2}}\)
3
\(\frac{{D_0^2 - D_i^2}}{{D_0^2}}\)
4
\(\frac{{D_i^2 - D_0^2}}{{D_0^2}}\)
