Sample ID
Weight of material retained on each sieve
Upper (a)
Middle (b)
Bottom Pan (c)
Sum of Weights
[d = a+b+c]
Calculations for percentage retained on each sieve
Upper [= a/d *100]
Middle [= b/d *100]
Bottom Pan [= c/d *100]
Calculations for percentage under each sieve
Upper Sieve
[e = 100 – (a/d*100)]
Middle Sieve
[f = e – (b/d*100)]
