Work on a consistent wet basis
Wet-basis moisture is water mass divided by total product mass. Use the same basis for starting and final moisture.

ENGINEERING GUIDE
What to check
Follow the solids
Assuming solids are conserved, divide dry solids by one minus the target moisture fraction to estimate dried product. Subtract that mass from fresh input for theoretical water removal.
Keep units tied to the process
For continuous production, use an hourly basis. For a batch, a cycle average needs the full cycle and turnaround time. Include cutting loss and downtime separately.
