The Hydrostatic Paradox
Engineering classes often discuss hydrostatics--the physics of non-moving water--before they cover fluid dynamics and its flows. But hydrostatics is plenty challenging on its own. (Video and image credit: S. Mould)
Unraveling the Growth Potential of the Geofoams Market: Global Outlook
The global geofoams market size is expected to reach USD 972.6 million by 2027, expanding at a CAGR of 2.7%, according to a new report by Grand View Research, Inc. Factors such as availability of geofoams at low cost coupled with its superior strength and durability are projected to fuel the market growth. Expansion of the construction industry across the globe coupled with the infrastructural developments in economies such as India, China, Brazil, Mexico, Saudi Arabia, and others is expected to propel the demand for geofoams over the forecast period. In addition, maintenance of the existing infrastructure in developed nations is likely to drive the growth of the market.
Geofoams Market Report Highlights
The expanded polystyrene geofoams segment accounted for USD 508.2 million in 2019 and is projected to expand at a CAGR of 3.1% from 2020 to 2027. The compatibility of the product has resulted in its increasing adoption for applications including roads and highway construction, building and infrastructure, and others
The road and highway construction application segment accounted for 38.07% of the total market and is projected to expand at a CAGR of 3.4% from 2020 to 2027 on account of the rising infrastructural growth across the developing economies including China, India, Brazil, UAE, Saudi Arabia, and others
Asia-Pacific accounted for USD 278.5 million in 2019 and is estimated to expand at a CAGR of 3.2% from 2020 to 2027 owing to the rising demand for road pavement, which is anticipated to further benefit the growth
China accounted for the highest market share in Asia Pacific on account of the rapidly expanding construction industry in the country
Europe market is estimated to expand at a CAGR of 2.8% owing to the rising number of construction and infrastructural activities in economies including Spain, Italy, and others

Geofoams are increasingly used in the construction industry as it helps in suppressing the noise and vibrations. In addition, it is easy to handle and does not require any special equipment for installation. The product is increasingly used in the railway track systems, below the refrigerated storage buildings, storage tanks, and others to avoid ground freezing.
The geofoams undergo chemical changes when it comes in contact with petroleum solvents. It turns into a glue-type substance, thereby losing its strength. This factor is projected to limit the use of geofoams in the construction industry which is projected to restrict the industry growth over the forecast period.
Pressure At The Dam
Hydrostatic pressure in a fluid is based on the fluid's depth. You'll rarely see a more dramatic example of that power than with a water release from a dam. (Image and video credit: Discovery UK; submitted by Olwyn B.) Read the full article
The Greedy Cup in Your Washing Machine
A Pythagorean, or "greedy" cup, is one that automatically drains itself once filled to a certain level. In other words, it's a self-starting siphon - one that triggers only at certain fill level. (Image and video credit: S. Mould) Read the full article
Why Aren't Trees Taller?
Trees are incredible organisms, with some species capable of growing more than 100 meters in height. But how do trees get so big and why don't they grow even taller? (Image and video credit: TED-Ed) Read the full article
You may have noticed a water tower rising up over your town, but you may not have given much thought to how it works. Practical Engineering has a nice video overview of this important piece of infrastructure, which municipalities use to store and pressurize water in public distribution systems.
During off-peak hours, pumps fill the water tower, which creates potential energy (and therefore, water pressure) that depends on the height of the water level. If you’ve ever lost power, you can appreciate how the water tower ensures that your faucet still runs. Without power, there are no pumps to pressurize the water line. But with the hydrostatic pressure of water in the tower, your water will still run like normal. For many people who live outside of municipal water zones, that’s not the case. A loss of power means an immediate loss of water also since the pumps that work their wells go offline. (Video and image credit: Practical Engineering)
Pressure is a concept that can be unintuitive, but it’s incredibly important in physics and engineering. So I’m excited to debut a collaborative video series that @mostlyenginerd and I are producing all about hydrostatic pressure! Today’s video is one of our openers: it focuses on where pressure comes from and why it’s a function of height but not volume. And to show you just how pressure increases with depth, we teamed up with divers from the Oregon State University Scientific Diving Team and headed to the Oregon Coast Aquarium’s Halibut Flats exhibit. Ever seen what a balloon looks like 7 meters underwater? You’re about to! (Video and image credit: N. Sharp and A. Fillo)

Our adventures with pressure continue after the trip to the aquarium. To see just how much pressure we could generate with height, A.J. and I teamed up with the Corvallis Fire Department to recreate an experiment attributed to 17th-century French physicist Blaise Pascal. In Pascal's experiment, he (supposedly) used a column of water to burst a wooden barrel. In ours, we use a ladder truck to make a 30-meter column of water burst a glass carboy! We also got a little help from our friends at the Lutetium Project to introduce you to Pascal and his work. (Thanks, Guillaume!) We'll tell you more about Pascal and his contributions in an upcoming video, so stay tuned. (Video and image credit: A. Fillo and N. Sharp)
