9 - Morphi: example of L/W distribution
  Species A Species B Comments
Length (mm) 0.480 0.484 Not significant
Coarseness
(mg.m-1)
0.141 0.153 On-line pb
0.95<L<1.3 mm
22<W<30 µm
0.3 4.0 Good
discrimination
   
10 - Mixed pulp: mean length
Variation of fiber mean length as a function of softwood
content. Are the results in agreement with the theory ?
 
     
 
11 - Mixed pulp: theory of mixing
   
12 - Mixed pulp: mean length
Comparison of calculated and experimental fiber mean
length (Rexp = 0.31)
 
     
 
13 - Mixed pulp: softwood content
Comparison of calculated and experimental softwood
content in mixed pulp
   
14 - Mixed pulp: coarseness formulas
 
     
 
15 - Mixed pulp: coarseness prediction
Comparison of calculated and experimental fiber
coarseness in mixed pulp
   
16 - Refining: fibers length repartition
Study the number of fibers in each length class
