Abstract
Jednoliko strujanje je strujanje koje ima stalan protok, stalnu protjecajnu površinu, stalan hidraulički pad, istu hrapavost omočene površine i ako ne postoje lokalni otpori. Brzinu takvoga strujanja računamo Chezyjevom ili Manning-Stricklerovom jednadžbom. Krivulja specifične energije presjeka sastoji se od dva kraka i oba teže u beskonačnost i pomoću nje možemo odrediti vrstu strujanja. Specifična energija presjeka je zbroj potencijalne energije koja ovisi o dubini vode u presjeku i kinetičke koja ovisi o srednjoj brzini vode u presjeka. Zbog nejednolike raspodijele kinetičke energije u složenom presjeku uvodi se Coriollisov koeficijent α. Protočna krivulja definirana je za svaki poprečni presjek posebno uzimajući u obzir nekoliko različitih protoka u tome presjeku i njegove odgovarajuće dubine. Protočna krivulja i specifična energija presjeka razlikuju se kod složenog i jednostavnog presjeka po tome što se oblik krivulje mijenja kod složenog presjeka nakon proširenja, a kod jednostavnog presjeka toga nema.
Abstract (english)
Uniform flow is a type of flow characterized by constant discharge, a steady flow cross-section area, a constant hydraulic gradient, uniform roughness of the wetted perimeter, and the absence of local obstructions. The velocity of such flow can be calculated by Chezy or Manning-Strickler equation. The specific energy curve of the cross-section has to branches and both tend towards infinity, and it helps determine the type of flow. The specific energy of the cross-section is the sum of potential energy, which depends on the depth of water in the cross-section, and kinetic energy, which depends on the average velocity of water in the cross-section. Due to the non-uniform distribution of kinetic energy in a complex cross-section, the Coriolis coefficient is introduced. Discharge - water depth curve can be defined for each cross-section, considering several different flow rates at that particular section and their corresponding water depths. Flow profiles and specific energy curves differ in cases of complex and simple cross-sections. The difference is in the shape of the curve; it changes in a complex cross-section after an expansion, while in a simple cross-section, this does not occur.
