Open Channel Hydraulics III: Sharp-Crested Weirs
This online engineering PDH video presentation is devoted to the more widely used sharp-crested weir. It places emphasis on the calculations used to measure for flow rate in various types of sharp-crested weirs. It presents guidelines for the installation, measurement and use of sharp-crested weirs in open channels.
A weir is basically an obstruction in an open channel flow path. Weirs are commonly used for measurement of open channel flow rate. A weir functions by causing water to rise above the obstruction in order to flow over it. The height of water above the obstruction correlates with the flow rate, so that measurement of the height of the flowing water above the top of the weir can be used to determine the flow rate through the use of an equation, graph or table. The top of the weir, which is used as the reference level for the height of water flowing over it, is called the crest of the weir. Weirs are typically classified as being either sharp-crested or broad-crested.
This 3 PDH online video presentation is intended primarily for civil, hydraulic, highway, environmental, chemical, mechanical, and industrial engineers, who are interested in learning more about open channel hydraulics.
This PE continuing education video presentation is intended to provide you with the following specific knowledge and skills:
- Familiarizing with standard terminology used in conjunction with sharp-crested weirs for open channel flow measurement
- Applying the Kindsvater-Carter equation to calculate the flow rate over a suppressed rectangular weir for given head over the weir and weir dimensions
- Applying the Kindsvater-Carter equation to calculate the flow rate over a contracted rectangular weir for given head over the weir and weir dimensions
- Knowing the conditions required in order to use the equation, Q = 2.49H2.48, for calculating the flow rate over a V- notch weir for given head over the weir and weir dimensions
- Applying the Kindsvater-Carter equation to calculate the flow rate over a V-notch weir for notch angles other than 90o, given head over the weir and weir dimensions
- Familiarizing with the installation and use guidelines for sharp-crested weirs for open channel flow measurement
