Hi everybody,
Sorry for my english, I'm a french speaker.
Is it possible to solve my problem in bika3?
In our laboratory, we have analysis on granulate (limestone) and we give
results in 2 types; >5mm and <5mm
Attention: the order of the sieves is important, because it's like this
we work.
First type: < 5mm:
sieves
Weight in g
Result in %
0.063mm
3.17
87.32
0.090 mm
0.98
96.08
0.100 mm
0.61
97.56
0.125 mm
0.16
99.36
0.200 mm
0.01
99.96
solde (rest)
25.00
* 25g is the weight of product we put on the first sieve (0.063 mm)
* In this type of results, the calculation is ((25g - weight on each
sieve)/25)*100
* There is no result for the rest
The second type of results > 5mm is like this:
sieves
Weight in kg
Result in %
25.0 mm
2.181
56.467
20.0 mm
1.62
24.132
12.50 mm
1.084
2.495
7.10 mm
0.107
0.359
solde (rest)
0.018
In this type of results, the calculation is like this; for example at
12.50mm:
* we calculate the total weight: 5.01 kg
* at 12.50 mm the result is: ((5.01 - (1.084+1.62+2.181)/5.01))*100
* it's the same for each sieve and there is no result for the rest
Actually, in our software, we say that for this equipment we use this
type of calculation
Best regards
