    Hong Kong Philharmonic Orchestra

    The Hong Kong Philharmonic (HK Phil) is one of Asia's leading orchestras. From the 2012/13 season, Jaap van Zweden has become Music Director of the orchestra. The HK Phil annually touches the lives of over 200,000 music lovers through more than 150 performances including its extensive education activities for children and adults alike, and free concerts such as the popular Swire Symphony under the Stars, and regular broadcasts and telecasts, bringing the joy of classical music to the Hong Kong community. Outside of Hong Kong, the HK Phil has made a number of critically acclaimed tours in Asia and Europe.

    What is Prestressed Concrete?

    What is Prestressed Concrete?

    Sometimes conventional reinforcement isn't enough. The basics of prestressed concrete. Prestressing reinforcement doesn't necessarily make concrete stronger. But, it does increase the serviceability of concrete members by reducing the amount of deflection under load. This video explains the two most common types of prestressed concrete: pre-tensioned and post-tensioned. Prestressed concrete is used in all kinds of structures from bridges to buildings to silos and tanks. It’s a great way to minimize cracking and take fuller advantage of the incredible strength of reinforced concrete.

    How Water Towers Work

    How Water Towers Work

    This video discusses the purpose and function of elevated water storage tanks. The job of finding enough water, making it safe to use, and then reliably distributing it to the system customers with almost no downtime is a monumental task that requires a lot of infrastructure. And, probably the most visible component of a public water system is the elevated storage tank, also known as a water tower.

    How Soil Destroys Buildings

    How Soil Destroys Buildings

    Expansive soils cause more property damage per year than earthquakes, floods, hurricanes, and tornadoes combined. Expansive soils are a slow-moving geologic phenomenon, which makes them not very news-worthy. However, they still cause a tremendous amount of damage to buildings and the public infrastructure we rely on every day.

    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.

    How to Collapse a Pipe by Closing a Valve

    How to Collapse a Pipe by Closing a Valve

    Water hammer can work in both directions, and I only discussed one of those in the previous video (https://youtu.be/xoLmVFAFjn4). This episode revisits that demonstration to show how water hammer can form a vacuum pressure in a pipe. Momentum carrying fluid away from a valve wants to keep going even after the valve is closed. This generates a negative pressure than can cause major damage!

    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.

    Why Bridges Move...

    Why Bridges Move...

    This video explains why ridges move, and other musings on thermal movement of large civil works. Most people have a certain intuition about thermal expansion, but you may not have considered how engineers design to accommodate it on large civil structures. The video gives a quick overview on this important consideration that engineers must account for when designing infrastructure like pipelines, bridges, and even sidewalks.

    What is Cavitation?

    What is Cavitation?

    This video shows the basics of fluid cavitation, including demonstration from AvE. If you subject a fluid to a sudden change in pressure, some interesting things can happen. You can cause tremendous damage to moving parts, or you can harness this destructive power in many beneficial ways.
