    What is Water Hammer?

    What is Water Hammer?

    Hydraulic transients (also known as water hammer) can seem innocuous in a residential setting, but these spikes in pressure can cause major damage to large pipelines and industrial pipe networks. In this video, we briefly discuss how water hammer occurs and how engineers mitigate the effect.

    What is Steam Hammer?

    What is Steam Hammer?

    A few things that can go very wrong when you put steam in a pipe. We talked about the damaging effects of water hammer, but there’s another state of H2O equally if not more dangerous when put in pipes. In this episode, we’re talking about steam hammer and differential shock.

    Welding 101

    Welding 101

    In general, and compared to other common building materials, metals have excellent mechanical properties. They are hard, tough, strong, and durable. As someone who occasionally works the wood, even I can admit that metals are a superior material in many regards. So you can see why it would be advantageous to have a way to connect them together, especially if you can do it in such a way that joint isn’t the weakest part of your assembly. That’s the goal of welding, and luckily, this is not something reserved for industrial factories and machine shops. From my own experiences so far, welding is something you might be able to do yourself as a hobby. And stay tuned till the end for some tips for getting started.

    Understanding Nuclear Energy

    Understanding Nuclear Energy

    In this nuclear energy course, we will tackle provocative questions such as: -Is nuclear energy a good substitute for fossil fuels to reduce our CO2 emission or not? -Can nuclear reactors operate safely without any harm to the public and environment? -How much nuclear waste is produced and how long does it need to be stored safely? -How can we make nuclear energy clean and more sustainable? -How much are nuclear energy costs? You will learn the physics behind nuclear science, how to gain energy from nuclear fission, how nuclear reactors operate safely, and the life cycle of nuclear fuel: from mining to disposal. In the last part of the course, we will focus on what matters most in the public debate: the economic and social impact of nuclear energy but also the future of energy systems. Practically, we will: -Teach you about nuclear science and technology (radiation and radioactivity, nuclear reactions, nuclear reactors and fuel cycle, economics of nuclear energy, and the sociality aspects) -Show you short videos about the theory and practical implementation of nuclear energy -Stimulate discussion and debate about nuclear energy -Ask you to formulate your own opinion about nuclear energy and its role in society The GENTLE consortium has sponsored and prepared this course. GENTLE is focused on maintaining the current high level of nuclear safety, and developing a highly skilled and well informed nuclear workforce, following the conclusion of the Council of the EU that it “it is essential to maintain in the European Union a high level of training in the nuclear field” to deal with reactor fleet safely, decommission obsolete plants, be involved in new builds where policy dictates, and deal with the legacy and future radioactive wastes.

    Treatment of Urban Sewage

    Treatment of Urban Sewage

    This course will focus on basic technologies for the treatment of urban sewage. Unit processes involved in the treatment chain will be described as well as the physical, chemical and biological processes involved. There will be an emphasis on water quality and the functionality of each unit process within the treatment chain. After the course one should be able to recognize the process units, describe their function and make simple design calculations on urban sewage treatment plants.
