Pulp Consistency & Water RatioPulp & Mill
Calculate dry fiber weight percentage in wet pulp slurry (consistency %) and water mixing dilution ratios for vat dipping.
Slurry density is assumed to match clean water (1 kg per Liter).
Proportion of dry wood fiber in wet water weight.
1 part dry pulp to X parts pure water weight.
Slurry Category: Standard Form Vat (0.2% - 0.8%)
Standard hand papermaking vat concentration. Yields smooth, even sheet profiles.
