The floating miracle: does pex pipe resist sinking?
What To Know
- Buoyancy is an upward force exerted by a fluid that counteracts the weight of an object submerged in it.
- Based on the density of PEX pipe and the principles of buoyancy, we can determine whether it floats or not.
- PEX pipe with a larger diameter has a greater volume and, hence, a higher buoyancy.
PolyEthylene Cross-linked (PEX) pipe has gained immense popularity in plumbing systems due to its flexibility, durability, and resistance to corrosion. However, a common question that arises is: “Does PEX pipe float?” The answer to this query lies in understanding the density of PEX and the principles of buoyancy.
Density of PEX Pipe
The density of a material is defined as its mass per unit volume. PEX pipe has a density of approximately 0.93 grams per cubic centimeter (g/cm³). This means that for every cubic centimeter of PEX pipe, it weighs 0.93 grams.
Buoyancy and Archimedes’ Principle
Buoyancy is an upward force exerted by a fluid that counteracts the weight of an object submerged in it. According to Archimedes’ Principle, the buoyant force acting on an object is equal to the weight of the fluid displaced by the object.
Does PEX Pipe Float?
Based on the density of PEX pipe and the principles of buoyancy, we can determine whether it floats or not. Since the density of PEX pipe (0.93 g/cm³) is less than that of water (1 g/cm³), it will experience an upward buoyant force that is greater than its weight. Therefore, PEX pipe will float on water.
Factors Affecting Buoyancy of PEX Pipe
While PEX pipe generally floats, certain factors can influence its buoyancy:
- Volume: The larger the volume of PEX pipe, the greater the buoyant force it experiences, making it more likely to float.
- Diameter: PEX pipe with a larger diameter has a greater volume and, hence, a higher buoyancy.
- Temperature: The density of water decreases with increasing temperature, which means that PEX pipe will float more easily in warmer water.
- Additives: Some PEX pipes may contain additives that increase their density, making them less buoyant or even causing them to sink.
Practical Applications of Floating PEX Pipe
The buoyancy of PEX pipe can be beneficial in certain applications:
- Submersible Pumps: PEX pipe can be used to connect submersible pumps to water sources, as it floats and provides flexibility in positioning.
- Floating Water Lines: In areas with shallow water bodies, PEX pipe can be used to create floating water lines for irrigation or water supply.
- Aquaculture: PEX pipe floats on water, making it suitable for use in aquaculture systems for fish farming and algae cultivation.
Final Thoughts: Unraveling the Mystery of Buoyancy
In conclusion, PEX pipe floats on water due to its density being lower than that of water. The buoyancy of PEX pipe is influenced by its volume, diameter, temperature, and any additives present. Understanding these factors allows for optimal use of PEX pipe in applications where buoyancy is crucial.
Quick Answers to Your FAQs
Q1: Why does PEX pipe float?
A1: PEX pipe floats because its density is less than that of water, creating an upward buoyant force that counteracts its weight.

A2: Volume, diameter, temperature, and additives can influence the buoyancy of PEX pipe.
Q3: Can PEX pipe be used in submersible applications?
A3: Yes, PEX pipe‘s buoyancy makes it suitable for use in submersible pumps and other underwater applications.
Q4: Is all PEX pipe buoyant?
A4: Generally, yes, but additives in certain PEX pipes may increase their density, reducing buoyancy or causing them to sink.
Q5: What is the density of PEX pipe?
A5: The density of PEX pipe is approximately 0.93 grams per cubic centimeter (g/cm³).
