What Really Happened at the Suez Canal? 0 (0)

From “Practical Engineering”. ( YouTube / Nebula ) Exploring the engineering principles behind the recent obstruction of the Suez Canal, which caused a weeklong disruption in global shipping traffic. I give a brief overview of the bank effect and dilatancy of coarse-grained soils. Hopefully, the video helps you understand a few of the engineering challenges…

What Really Happened During the Texas Power Grid Outage? 0 (0)

From “Practical Engineering”. ( YouTube / Nebula ) When disaster strikes, the flurry of political positioning and fingerpointing can make it difficult to understand what really happened. This video provides a summary of the facts of the 2021 Texas winter storm. ⚡ My playlist about the electrical grid: https://youtube.com/playlist?list=PLTZM4MrZKfW-ftqKGSbO-DwDiOGqNmq53 📄 Most of the energy statistics…

What Is a Culvert? 0 (0)

From “Practical Engineering”. ( YouTube / Nebula ) Discussing the hydraulics of the humble highway culvert. Culverts are ubiquitous in the constructed world. They seem so obvious that you may never consider them. But, the engineering behind culverts is quite complicated and exciting. Next time you’re driving or walking along a street, keep an eye…

The Surprising Efficiency of Canal Locks 0 (0)

From “Practical Engineering”. ( YouTube / Nebula ) People use boats for all kinds of reasons, and in the same way, there are all kinds, shapes, sizes, and ages of locks used for waterway navigation across the world. Freight is big business. “Shipping” got its name for a reason, and we still use ships to…

Why Pipes Move Underground 0 (0)

From “Practical Engineering”. ( YouTube / Nebula ) Discussing thrust forces in pipelines (with the help of our friends at Air Command Rockets). Huge thanks to @Air Command Rockets for collaborating on the video. Go check out their channel for tons of awesome content on water rockets. We use pipes to carry all kinds of…

What is Air Lock? 0 (0)

From “Practical Engineering”. ( YouTube / Nebula ) A demonstration and brief explanation of air lock in fluid pipelines. If you assume that gasses don’t get into pipes or that they can’t constrict the flow, you might design a pipeline that doesn’t work. Luckily for engineers, this is a well-known phenomenon in pipe systems. It’s…

How Power Blackouts Work 0 (0)

From “Practical Engineering”. ( YouTube / Nebula ) Exploring the protective systems that keep the power grid from self destructing. We usually think of the power grid in terms of its visible parts: power plants, high-voltage lines, and substations. But, much of the complexity of power grid comes in how we protect it when things…

How do Electric Transmission Lines Work? 0 (0)

From “Practical Engineering”. ( YouTube / Nebula ) Discussing some of the fascinating engineering that goes into overhead electric power transmission lines. In the past, power generating plants were only able to serve their local areas. As power plants grew larger and further away from populated areas, the need for ways to efficiently move electricity…
