Two phase discharge flow prediction in safety valves [PDF]

open access: yes, 2013
Safety Relief Valves (SRV) are necessary elements in the protection of any pressurised system and the prediction of the expected discharge flows is an important consideration for the valve sizing to ensure that rupture pressures do not occur.

Experimental and numerical analysis of flow over a rectangular full-width sharp-crested weir

open access: yesWater Science and Engineering, 2018
Weirs are a type of hydraulic structure, used for water level adjustment, flow measurement, and diversion of water in irrigation systems. In this study, experiments were conducted on sharp-crested weirs under free-flow conditions and an optimization ...

The effect of crest shape on discharge coefficient at linear weirs

open access: yesGrađevinar, 2023
A detailed experimental laboratory analysis of the effect of crest shape on the discharge coefficient of sharp-crested weirs is presented in the paper. The experiments were conducted for four different crest shapes. The experiments and analyses show that

Discharge estimation in a backwater affected meandering river [PDF]

open access: yes, 2011
Variable effects of backwaters complicate the development of rating curves at hydrometric measurement stations. In areas influenced by backwater, single-parameter rating curve techniques are often inapplicable.

Discharge coefficients for ogee spillways

open access: yesWater Supply, 2022
Abstract Discharge over an ogee weir is related to the length of the weir, upstream total head above the weir crest and the discharge coefficient. The discharge coefficient is influenced by several factors; in this study, some parameters that influence discharge coefficients of ogee weirs are investigated. These factors include: the weir

Emitter discharge variability of subsurface drip irrigation in uniform soils: effect on water-application uniformity [PDF]

open access: yes, 2008
Emitter discharge of subsurface drip irrigation (SDI) decreases as a result of the overpressure in the soil water at the discharge orifice. In this paper, the variation in dripper discharge in SDI laterals is studied.
