Effect of downstream apron elevation and downstream submergence in discharge coefficient of ogee weir

ISH Journal of Hydraulic Engineering, 2018
Discharge coefficient in ogee spillways is essential factor for producing discharge–head relationship. Discharge coefficient is relevant to the downstream water level submergence and downstream apron elevation.

Calculation of the Townsend Discharge Coefficients and the Paschen Curve Coefficients

Contributions to Plasma Physics, 2007
AbstractThe determination of Paschen curve coefficients A and B and the first and second Townsend coefficient are discussed for the creation of gas discharges from extraordinary gasses. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

ِِDischarge Coefficient in Oblique Side Weirs

2007
Side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. The present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels.

Discharge Coefficients of Chamfered Orifices and Nozzles

Aircraft Engineering and Aerospace Technology, 1948
REFERENCE has frequently been made to the increase in the discharge coefficient of chamfered orifices and nozzles, yet few investigations have been made to study these variations in detail. The experiments described in the following were carried out in an attempt to clear some of these points.
