Calculadora de Volume de Tubulação Online Grátis
Volume capacity and flow rate of cylindrical pipes with unit conversion
The Pipe Volume Calculator finds the internal volume of a cylindrical pipe or tube from its bore diameter and length, with full unit conversion between litres, gallons, cubic metres, and cubic feet. Plumbers, HVAC engineers, and process piping designers use it to size water storage in pipework, calculate fill/drain times, and determine the mass of fluid-filled pipe runs.
Frequently Asked Questions
Sobre Esta Calculadora
The volume of fluid in a pipe run has direct engineering implications: a large-diameter heating main holds hundreds of litres of water, which affects boiler sizing, pressurisation vessels, and the time and energy needed to heat the system from cold. For gas pipelines, the volume determines purge requirements. For fuel lines, it affects priming procedures and pressure loss calculations.
The formula is simple — π × radius² × length — but the practical challenge is keeping units consistent when pipe diameters are often given in millimetres while lengths are in metres or feet. This calculator handles all unit combinations and outputs volume in litres, US gallons, imperial gallons, cubic metres, and cubic feet simultaneously.
Process engineers and facility managers also use the pipe volume to calculate the weight of filled pipe runs for structural loading, the glycol volume needed for freeze protection in HVAC systems, and the water volume for chemical dosing calculations in industrial water treatment.
A Calculadora de Volume de Tubulação encontra o volume interno de um tubo cilíndrico a partir do seu diâmetro interno e comprimento.
Fórmula
Volume = π × (Diameter/2)² × Length
Exemplo Resolvido
Volume of water in a 50 m run of 100 mm bore pipe
Entradas:
- Internal diameter: 100 mm (0.1 m)
- Length: 50 m
Passo a Passo:
- Radius = 0.1 ÷ 2 = 0.05 m
- Cross-sectional area = π × 0.05² = π × 0.0025 = 0.007854 m²
- Volume = 0.007854 × 50 = 0.3927 m³
- Convert to litres: 0.3927 × 1,000 = 392.7 litres
- Weight of water: 392.7 × 1 kg/litre = 392.7 kg ≈ 393 kg
