Description

Measurements were taken on a three-foot Cutthroat flume in a hydraulics laboratory to determine the effects of non-hydrostatic flow conditions on calibrations for flow measurement. Four different throat widths were included in the study, which involved both free- and submerged-flow conditions. The effects of non-hydrostatic pressure distributions at the upstream and downstream measurement taps were documented, and suggestions are given for modifying the calibration procedures when non-hydrostatic conditions present themselves. Standard calibration parameters were also determined for the three-foot Cutthroat flume, and significant differences were obtained when compared to previously published values.
