Tank Fill / Empty Time

Time to fill or empty a tank given inlet/outlet rates.

What this workbook is

A real, downloadable Microsoft Excel workbook — not a rendered demo. Every sheet is built around a single engineering method: inputs in one place, calculated results and a PASS / WARN / FAIL check sheet, with the method, sources and assumptions recorded next to the numbers. Open it in Excel, Sheets or LibreOffice, change the inputs, and the workbook recalculates.

  • Light cells are user-entered inputs on the Inputs sheet.
  • Dark cells are calculated automatically and are not editable.
  • The method and sources for every calculation are listed below and inside the workbook.

What you enter

  • Tank capacity
  • Inlet flow

What it calculates

  • Net fill rate
  • Fill time (h)

Method

t = V / (Qin − Qout); unit-consistent
