The rate of flow through a Parshall flume is determined by the measurement of which of the following?
  1. Water velocity
  2. Flume configuration
  3. Water depth
  4. Water area
Explanation
Answer: C - The rate of flow through a Parshall flume is determined by the measurement of water depth. Parshall flumes are specially shaped channel flow sections that are installed in gravity conveyance systems. These flumes conform to sizing standards set by the U.S. government. With recent advancements in flow monitoring technologies, Parshall flumes are not as widely used now as they had been in the past.
