How worksheets differ from single calculators

  1. 1Start with the job intent: hydraulic design, battery and NAC review, water supply, pump selection, or hazard setup.
  2. 2Use the input matrix to confirm where each value comes from before opening linked calculators.
  3. 3Run phases in order and keep the QA gates and saved records with the calculation package.
