The main problem in the operation of irrigation systems is to ensure accuracy and reliability measuring hydrometric parameters managing water resources facilities. When operating with pumping stations, it becomes necessary measure a set technological parameters, which can be divided into following groups by type: hydraulic (flow rate, fluid pressure, flow channel), units, linear-angular (channe...
Dünyada yaklaşık 332,5 milyon kübik mil sudan oluşan su kaynaklarının %96’sı okyanus ve denizleri içeren tuzlu kaynaklarıdır. Geriye kalan %4’lük tatlı %68’i buzullarda sıkışmış halde bulunurken, %30’u ise toprak altı suyu olarak yer almaktadır. Kullanılabilir doğal nedenlerle bu kadar az olmasının yanı sıra; sanayileşme kentleşmenin yarattığı çevre kirliliği, sera gazı emisyonlarının sürekli ö...
a new method was introduced for frothing characterization of flotation frothers. method uses water recovery to develop a new frothability index named water recovery index (wri). new index was determined for some commercial frothers and results were compared with dynamic frothability index (dfi). results showed that water recovery index values follow the order of a-65 13016 s/mol > df-250 6292.4...
The adsorbed film of 1-decyl-3-methylimidazolium bromide (DeMIMB) at the air/water interface was investigated employing the surface tension measurement and the x-ray absorption fine structure method under the total reflection condition (TRXAFS). From the surface tension measurement, the surface excess concentrations of ions were determined. From the XAFS measurement, two solvation states of bro...
