| 1. | Open channel flow meters measure upstream levels in front of flumes or weirs.
|
| 2. | The tank effected a transition between open channel flow and a lead pipeline.
|
| 3. | The volumetric discharge, Q is typically used in open channel flow calculations.
|
| 4. | This equation is used both for open channel flow as well as in pipe flows.
|
| 5. | The weirs are intended to measure no more than 35 % of the pipe's open channel flow capacity.
|
| 6. | The diagram at the left shows some parameters and terminology used with a sharp crested weir for open channel flow rate measurement.
|
| 7. | Unlike most other flumes used for open channel flow measurement, the Palmer-Bowlus flume can be calibrated by theoretical analysis.
|
| 8. | The v notch weir is one type of sharp crested weir for which background information is given in Open Channel Flow Measurement 1.
|
| 9. | In open channel flow, the wetted perimeter is defined as the surface of the channel bottom and sides in direct contact with the aqueous body.
|
| 10. | In an open channel flow, this manifests as the fast flow rapidly slowing and piling up on top of itself similar to how a shockwave forms.
