Answer 2

Answer:

The answer is Large

In sampling of solid bulk ratio should be as large as possible

Explanation:

• The sampling of solids are difficult because solids are heterogeneous in nature.
• If there are impurities in the solid sample it may leads to error in sampling.
• This error can be reduced by crushing the large sample to small samples or by taking large quantity of the sample.
• "Coning and Quartering" is another method for sampling the heterogeneous material.
• The bulk ratio is important in the solid sampling.

$Bulk ratio = \frac{Weight of the sample}{Total weight of the bulk material}$    ...........................(1)

$Size to weight ratio = \frac{Weight of the largest particle}{Weight of the sample}$    ..................(2)

• To determine the number and size of increment of the solid particle this concept is applied.
• For sample which is true representative of bulk material bulk ratio of the sample should be large and the size to weight ratio should be small.
