Formula
4 ÷ 3 × π × (diameter ÷ 2)³ × 1000
Result unit: L

V = (4/3)πr³ = πD³/6. ×1000 converts m³ to liters. Spheres are optimal for pressurized storage (minimum wall stress per unit volume).

Introduction

Calculate volume of a sphere from diameter. Spherical tanks are widely used for LPG, propane, butane, and cryogenic storage because their shape provides uniform stress distribution under pressure, minimizing wall thickness requirements.

Calculation Example

10m diameter sphere = 523,599 liters (~524 m³) — typical small LPG sphere.

Inputs: diameter=10
Result: 523599 L

Engineering Applications

  • •LPG/propane storage
  • •Cryogenic tanks
  • •Gas holders
  • •Pressure vessels

Frequently Asked Questions

Why use spherical tanks for pressurized storage?

A sphere has minimum surface area per unit volume and uniform membrane stress distribution, requiring less steel than a cylinder for the same pressure and volume.

What are standard sphere sizes?

Common sizes range from 100 m³ (6m diameter) to 10,000 m³+ (27m diameter) for refinery and petrochemical applications.
