As the ASTM grain size number increases, the number of grain per unit volume will ______________

As the ASTM grain size number increases, the number of grain per unit volume will ______________ Correct Answer increase

The ASTM grain size number is given by: -> G=-2.9542+1.4427 ln na So as the value of G increases, na will also increase (number of grain in per mm square increase). So the number of grain per unit volume will also increase.
