Storage Capacity Calculator

Calculate liquid storage capacity for multiple tanks or vessels, with days-of-supply estimation.

Inputs

Formula
volume × fill ÷ (consumption × 3600 × 24)
Result unit: days

Days = (Volume × FillFactor) / (Consumption × 86400). Volume in m³, consumption in m³/s (×3600×24 to m³/day).

Introduction

Calculate how many days of supply a tank farm provides given total storage volume, a fill factor (ullage), and process consumption rate. API standards typically recommend 7-30 days buffer for raw materials.

Calculation Example

100,000 L at 90% fill = 90 m³ usable. At 0.375 m³/h consumption (9 m³/day): 37.5 days of supply.

Inputs: volume=100000, fill=0.9, consumption=0.1
Result: 37.5 days

Engineering Applications

  • •Tank farm sizing
  • •Supply chain planning
  • •Buffer stock calculation
  • •Process plant design

Frequently Asked Questions

What is a good fill factor?

Storage (m³) = daily consumption × 7 / fill factor. For 10 m³/h = 240 m³/day × 7 / 0.9 = 1,867 m³ needed.
