The image above represents grain size determination. To calculate average number of grains per square inch, one essential parameter is needed and this parameter is ASTM Grain Number (n).
The formula for calculating average number of grains per square inch:
No = 2(n – 1)
Where:
No = Average Number of Grains per Square Inch
n = ASTM Grain Number
Given an example;
Find the average number of grains per square inch when the ASTM grain number is 2.
This implies that;
n = ASTM Grain Number = 2
No = 2(n – 1)
That is, No = 2(2 – 1)
No = 2(1)
No = 2
Therefore, the average number of grains per square inch is 2.
