# Weight of Sea Water in a pipe

KurtHeckman.Weight of Sea Water in a pipe

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:

- M is the mass (weight) of seawater in the pipe
- μD is the density of seawater
- D is the diameter of the pipe
- L is the length of the pipe

The mass is calculated based on the following equation:

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.
