Every lover I've had ends up conflating Bon Iver with me, even if they knew it before they met me. Regardless of where I am in my life, the music seems to readjust with me and make itself relavant and salient. Since then, Justin Vernon's music, particularly Bon Iver, has always been something that I feel close to. To me all of those songs seemed caught up in love and love lost and it had such a mournful quality to it, but it seemed so sincere and authentic. It was one of the first nights I fell asleep listening to music all night long, and I would wake up and hear various parts of those songs, and it was among the first times I realized music could incept a longing or a nostalgia for something you never really had or knew. That night I downloaded Flume, Lump Sun, Blood Bank, Babys, and one more off For Emma that I can't recall. But he seemed genuinely enthused that I liked the music he was playing. It means good winter." I was the sort of student who I think frustrated my teacher somewhat I wasn't good at math, and I could be a little disruptive. He said, "Bonnie Ver," I asked him to repeat himself, and he said, "It's French. I raised my hand and my teacher came over and I asked him who was playing. Anyway, the chorus of Flume came on and it had that quality that seems to reframe everything you're perceiving in a new light. My teacher always played music during tests, usually it was acoustic blues and what I had always assumed was called folk. 1.I was sitting in high school geometry class one February in 2009, taking a test. H is the head at the primary point of measurement.C is the free-flow coefficient for the flume.The free-flow discharge can be summarized as Under free-flow conditions, the depth of water at a specified location upstream of the flume throat can be converted to a rate of flow. The Parshall flume accelerates the flow through a contraction of both the parallel sidewalls and a drop in the floor at the flume throat. Soil Conservation Service, the Parshall flume is a fixed hydraulic structure used in measuring volumetric flow rate in surface water, wastewater treatment plants, and industrial discharge applications. The Parshall flume is a modified version of the Venturi flume. Parshall flumes (right) alongside other types of flow meters Diagram of a Parshall flume, showing free-flow and submerged flow operating regimes 90% is viewed as the upper limit for which corrections for submerged flow are practical. The secondary point of measurement (Hb) for a Parshall flume is located in the throat, measuring Hb can be difficult as flow in the throat of the flume is turbulent and prone to fluctuations in the water level. Submergence transitions for Parshall flumes range from 50% (1–3 inch sizes) to 80% (10–50 foot sizes), beyond which point level measurements must be taken at both the primary and secondary points of measurement and a submergence correction must be applied to the flow equations. The flumes are not patented and the discharge tables are not copyright protected.Ī total of 22 standard sizes of Parshall flumes have been developed, covering flow ranges from 0.005–3,280 cfs (0.1416–92,890 L/s). The design of the Parshall flume is standardized under ASTM D1941, ISO 9826:1992, and JIS B7553-1993. Some states specify the use of Parshall flumes, by law, for certain situations (commonly water rights). The Parshall flume accelerates flow through a contraction of both the parallel sidewalls and a drop in the floor at the flume throat. It is used to measure volumetric flow rate in industrial discharges, municipal sewer lines, and influent/effluent flows in wastewater treatment plants. The Parshall flume is a fixed hydraulic structure. The Parshall flume is an open channel flow-metering device that was developed to measure the flow of surface water and irrigation flow.
