Calibration Of Weirs By Means Of Critical Flow And Specific Energy, Robert A. Rapp
Masters Theses
"For many years man has been relying more each day upon metering devices to measure the flow of fluids in industry. The orifice, orifice meter, venturi meter, pitot tube, nozzle, flume and the weir have been employed, each having its own particular advantage.
In this parade of metering progress, the contracted weir has long been the forgotten brother of the suppressed weir. In almost every textbook on hydraulics or fluid mechanics, the following words appear, "end contractions are to be avoided where the weir cannot be calibrated". This skepticism and the length or absurdity of some contracted weir formulas led …
