Discharge over a tapered weir
The flow rate measurement in a rectangular weir is based on the Bernoulli Equationprinciples and can be expressed as: cd must be … See more The triangular or V-notch, thin-plate weir is an accurate flow measuring device particularly suited for small flows. For a triangular or v-notch weir the flow rate can be expressed as: See more For measuring the flow rate it's obviously necessary to measure the flow levels, then use the equations above for calculating. It's common to measure the levels with: 1. ultrasonic level … See more WebWeir shapes used for flow measurement are discussed further in Section 14.14. The discharge coefficient can vary significantly from the basic broad-crested value of 1.705 and depends largely on the geometry of the crest, but it is also a function of the depth and velocity of the approach flow.
