What is it's use

It is able to calculate all of the most important technical characteristics of the felt using equations deriving from physics of porous means, for example:
· distance between fibers in micron;· open surface in cm2/m2;· length, diameter, tortuosity of capillaries in mm and micron;· % of contact surface;· % of achievable dryness;· effective pressure of the fibers on paper in Kg/cml;· pressure drop at the suction box expressed as the sum of the loss of loading in every section of the felt in mH20;· new felt thickness, compressed felt thickness and critical thickness in mm;· total deformation and deformation of every section of the felt in mm;
· total weight and weight of every section of the felt in gsm;
· total air permeability and permeability of every section of the felt in cfm;
· width of the nip in mm with and without the felt;
· water eliminated in l/s;
· drain speed in mm/s;
· active volume in cm3/m2;
· operating void volume in cm3/m2;
· optimal needling density in strokes/cm2;
· optimal needling depth in mm.
