This Plumbing Pipe Volume Calculator allows you to estimate the volume of a pipe given its dimensions as well as the weight of a liquid that flows through it.
What is a pipe volume calculator?
A pipe volume calculator is an online tool designed to estimate the volume of a pipe along with the mass of a liquid that flows through it. It typically requires input parameters like the diameter and length of the pipe, as well as the type of material used in the pipe’s construction.
Who uses a pipe volume calculator?
This type of calculator is helpful for anyone who needs to know the exact volume of a pipe. Engineers rely on pipe volume calculators to design efficient piping systems, while plumbers use them to ensure optimal flow rates. Construction pros leverage this tool to estimate materials, and DIY homeowners use it to inform simple home projects, like filling/refilling a garden pond.
How accurate are the results from pipe volume calculators?
The accuracy of the results will depend on the accuracy of the info entered and the assumptions made by the calculator. For more precise engineering applications, we’d suggest verifying the accuracy of the calculator against known standards or performing manual calculations when necessary.
Can I use the pipe volume calculator for pipes made of different materials?
Yes, the pipe volume formula applies to pipes made of various materials. This includes copper and other metals, plastics, and concrete. However, material properties like density may need to be considered separately for specific applications—for instance, when you’re calculating the weight of the material.
Pipe Volume Formula
V = π × r² × h
Where:
– V is the volume of the pipe.
– π is the mathematical constant pi (approximately 3.14159).
– r is the radius (half diameter) of the pipe.
– h is the height or length of the pipe.
To calculate piping size, follow these steps:
– Find the inner diameter and length of the pipe, in inches or millimeters.
– Calculate the inner diameter of the pipe by measuring the distance from one inside edge, across the center, to the opposite inside edge.
– Use the same units (inches or millimeters) to measure the length of pipe.
– Calculate the radius of the pipe through its diameter. To get the radius, divide the diameter by 2.
– Take the radius and square it, or multiply it by itself. For instance, 5² = 25.
Example of How to Calculate Pipe Volume:
Here’s a specific example of how to apply the pipe volume formula:
For a 1-inch pipe that measures 8.333 feet long:
radius = 1 inch / 2 = 0.5 inch
length = 8.333 × 12 inches = 100 inches
volume = π (pi) × radius squared × length
volume = 3.141822048 × (0.5 × 0.5) × 100
volume = 3.141822048 × 0.25 × 100
volume = 1,963.6388 in³
Volume of Pipe Calculator in Cubic Centimeters:
1 cubic inch = (25.4)3 cubic millimeters
1 cubic inch = 16,387.064 cubic millimeters
volume = volume in in³ × 16,387.064 cubic millimeters
volume = 1,963.6388 × 16,387.064 cubic millimeters
volume = 32,178,345.052 mm³
Volume of Pipe Calculator in Gallons:
There are 231 cubic inches in 1 U.S. gallon.
volume = volume in in³/231 gallons
volume = 1,963.6388/231 gallons
volume = 8.5006 gallons
Volume of Pipe Calculator in Liters:
1 cubic inch = 0.016387 liters
volume = volume in in³ × 0.016387 liters
volume = 1,963.6388 × 0.016387 liters
volume = 32.17835 liters
