How to Use This Calculator
  1. Enter the oven-dry fiber weight (kg) in your stock sample or batch.
  2. Input the total slurry weight (kg) including fiber and water.
  3. Set the target consistency (%) for the next process stage.
  4. Enter the stock flow rate (L/min) to calculate fiber throughput.
  5. Review Current Consistency (%), Water Change needed (L), Fiber Flow (kg/min and t/day), and Consistency Category.
