Discharge Coefficient for Siphon Spillways
Journal of Irrigation and Drainage Engineering, 2013AbstractThe study deals with the discharge coefficient for siphon spillways based on the results of experimental methods and numerical simulations. Siphon spillways are used as the outlet in reservoirs to control the incoming flood flows. A scaled plexiglass model of a siphon was fabricated and tested in the laboratory flume to determine the siphon ...

Coefficients of Discharge at the Aperatures of Engines
SAE Technical Paper Series, 1995<div class="htmlview paragraph">This paper reports on the experimental evaluation of certain aspects concerning the mathematical modelling of pressure wave propagation in engine ducting. A particular aspect is the coefficient of discharge of the various ports, valves or apertures of the ducting connected to the cylinder of an engine or to the ...

Four ASME (PTC 6) flow nozzles were manufactured together with upstream and downstream pipework in two pipe sizes. Throat and wall tappings were used. The flow nozzles were calibrated in water and in high-pressure nitrogen at 20 and 60 barg. The wall-tapping data are in excellent agreement with the discharge-coefficient equation in ISO 5167-3:2003: all

The discharge coefficient is required to measure flow using a differential-pressure meter. This chapter considers the discharge-coefficient equation for orifice plates: its history, some older equations, the database collected mostly in the 1980s and the analysis.

The discharge coefficient of effervescent atomizers
Experimental Thermal and Fluid Science, 2010Abstract The paper contains the results of experimental investigation of air–water atomization process in effervescent nozzles with internal mixing. The aim of study was analysis of pressure drop and discharge coefficient. The study was carried out at liquid flow rates changed from 0.0014 to 0.011 [kg/s] and gas flow rates from 0.00015 to 0.0065 [kg ...

Discharge coefficient of subsurface weirs
Proceedings of the Institution of Civil Engineers - Water Management, 2014Experimental and numerical studies were performed to examine the relationship between the hydraulic properties and physical dimensions of a subsurface weir system and the discharge over it under steady-state conditions. Experimental modelling was based on a laboratory-scale physical sand-tank model, within which a subsurface dam and weir structure was

Discharge coefficients of diaphragms and nozzles
Measurement Techniques, 19591. The table of initial discharge coefficients of diaphragms should be corrected by taking the coefficient value 0.646 (instead of 0.645) for the 0.35 modulus. 2. The functional dependence of the initial discharge coefficient on the modulus of flow-contraction devices, represented by a polynomial of the 4th degree, yields deviations from
