Like settling, corrections for submergence have been developed.įinally, if there is a flow that is used with the flume, the location and calibration of that meter should be checked. Submergence will result in the flume overreading the actual flow rate. If upstream and downstream flow lines are close in elevation, the flume has been experiencing submergence for an extended period of time. Check the flow line of the flume - the high water mark along the wall.If the flume has a staff gauge, take a look to make sure that gauge is readable - cleaning or replacing as necessary. Flume can be a noun or a verb, and it refers to a deep narrow passage or ravine with a stream, an artificial channel for water, or an amusement park ride.It has a simple and flexible architecture based on streaming data flows. Verify that the channel hasn’t experienced overtopping since the last inspection. Apache Flume is a distributed, reliable, and available service for efficiently collecting, aggregating, and moving large amounts of log data.Maintenance may have to be performed to remove sediment and debris. That the channel upstream and downstream of the Parshall Flume hasn’t changed and that vegetative growth isn’t impacting flow - particularly out.Verify the sidewalls are vertical - that frost heave, settlement, or soil conditions haven't bowed the walls.The Parshall Flume is still in dimension - within 2% of the nominal dimensions.That the Parshall Flume’s flow surfaces are free of algae and other biological growth.If the flume has shifted - but otherwise in dimenision - corrections for settelment have been developed to still allow you to use the flume.The Parshall Flume hasn’t shifted out of position due to frost heave, animal traffic, or subsidence.Generally, before the flow season begins, it’s recommended that you do a site inspection. Now that doesn’t meant that you don’t need to periodically check to make sure the Parshall Flume isn’t clean and level, or that the upstream / downstream conditions haven’t changed - because they do! The dimensions and applications of this flume are entirely up to my discretion, and the DKC is aiding me in the process in ways such as supplying me with materials and teaching me to use 3D printing technology.One of the advantages of using a device like a Parshall Flume is that, properly installed and applied, there is NO NEED TO CALIBRATE THE FLUME! A flume is a specially shaped structure with an area and/or slope that is different from the channel in which it is placed. The Digital Knowledge Center is granting me the ability to design and construct my own flume to be used for future research with the Physics Department. However, I envisioned the a flume that could be used in the Physics Department, that had different specifications. The flume built for my research project was designed to meet certain specifications, particular to the needs of the Geography Department. The work of Flume is to catch streaming data from various sources such as social media clouds, various web servers etc. It is a very basic three-step procedure to understand the working of Apache Flume. Thus, flumes are versatile machines that can have applications in a variety of fields, where their shape and size is manipulated. Here is a small diagrammatic representation that will make this entire process very easy for you to understand. And in Physics, we observe the way that water transitions through different kinds of flow-types, as we create obstructions. In Geography, the flume is being constructed to observe sediment distribution, eddy formation, and erosion. Similarly, Disney World uses flumes to transport cars around water roller coasters. The first flumes date back to the mid-1800s, where they were used by logging companies to easily and efficiently transport logs down mountains, using the negative incline. Water is then released or pumped across the length of the box, which can then be measured, observed, and exploited for energy. Believe it or not, all of these concepts begin with Physics! What are flumes?įlumes are man-made channels, typically constructed of glass or a composite plastic, like plexiglass, that runs water through it for a number of purposes. Last semester, I began a research project with Physics and Geography Department, to design, produce, and test a flume that could have physical applications for the Geography Department. In physics, we call this the Fluid dynamics. A large portion of my education has been dedicated to the research, understanding, and application of fluids, namely water. I’m Boone Fleenor, a sophomore here at Mary Washington studying Applied Physics and Mathematics, and I am a new DKC Fellow.
