The Weight of Seawater in a Pipe calculator computes the weight (mass) of seawater in a pipe based on the density of the seawater (saltwater), the diameter and length of the pipe.

INSTRUCTIONS: Choose units and enter the following:

  • (D) This is the diameter of the pipe.
  • (L) This is the length of the pipe. 
  • (μD) This is the density of the seawater.

Weight of Seawater in a Pipe (M): The calculator returns the mass in kilograms.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The Weight of Sea Water in a pipe is calculated using the dimensions of the pipe (length and diameter) and the of the density of sea water.  The formula for the weight of seawater in a pipe is:

           M = μD • π • (D/2)² • L

where:

The mass is calculated based on the following equation:

              mass = density • volume

Volume is calculated using the volume of a pipe equation.  And the mean density of sea water is a vCalc constant equal to 1,025 kilograms per cubic meter.
