Dorry Abrasion Test:
The Dorry Abrasion Test is used to determine the hardness of stones. It is conducted by subjecting the specimen to the action of a standard abrasive disc under specified conditions. The loss in weight of the specimen due to abrasion is determined and expressed as a percentage of the weight of the specimen before abrasion. The coefficient of hardness is the reciprocal of this percentage.
Calculation:
Given, the loss in weight = 21 gms
Coefficient of hardness = 1/percentage loss in weight
We need to calculate the percentage loss in weight first.
Let the weight of the specimen before abrasion be W.
Then, percentage loss in weight = (loss in weight/W) x 100
= (21/W) x 100
Coefficient of hardness = 1/(21/W) x 100
= (W/21) x 100
We do not have the weight of the specimen, so we cannot calculate the exact value of the coefficient of hardness. However, we can see that the coefficient of hardness is directly proportional to the weight of the specimen. So, a heavier specimen will have a higher coefficient of hardness than a lighter specimen.
Answer:
The correct option is D) 13.
