Pipe Volume

The Pipe Volume calculator                                Section of Pipe   computes the volume of a pipe (V), based on the interior diameter(d) of circular conduit or pipe and the length (l) of the pipe. 

INSTRUCTIONS: Choose units and enter the following:

• (D) Inner Pipe Diameter.
• (L) Pipe Length.

Volume of Pipe (V):  The calculator returns the volume in gallons.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The equation for the volume of a pipe is:

V= π⋅(D/2)²⋅L

where:

• V = interior volume of a section of pipe
• D = inner diameter
• L = length of pipe

Plumbing Calculators

• Rolling Offsets (Run and Travel)  – The Rolling Offset Rolling Offset Lengths Pipe Grading function computes the run and travel length a rolling offset based on the offsets and fittings. (see diagram).
• Pipe Grading - Compute the drop needed over a run to maintain a grade (e.g., 4" over 12')

• Pipe Stress Budget - Computes the pressure that a pipe can withstand based on the allowable stress, wall thickness and outside diameter.
• Water in Basement Volume: Computes the volume of water in an area such as a basement based on the dimensions and the time required to pump it out based on a sump pump rate.
• Paint for Pipes: Computes the amount of paint needed to cover the exterior surface area of one or more pipes based on the pipe diameter, length, number of coats, number of pipes and the recommended area coverage of the paint. 
• Time to Fill: Computes the amount of time necessary to fill something (e.g., tank or pool) based on the volume and flow rate.
• Pipe Insulation Calc: Computes the number of bags of pipe insulation needed for a run of pipes based on the 12' of length per bag and the length of pipe run to be insulated.
