Qonda ifomula yokubala izinga lokugeleza kwevolumu ngokusebenzisa i-weir

Ama-Weirs avame ukusetshenziswa njengendlela elula nephumelelayo lapho kulinganiswa ukugeleza kwamanzi eziteshini ezivulekile. I-weir iyisithiyo ebubanzini bomsele ovulekile lapho amanzi ageleza khona. Ngokulinganisa ukugeleza kwamanzi e-weir, izinga lokugeleza kwe-volumetric, okuyivolumu yamanzi adlula endaweni ethile enqamulayo ngesikhathi seyunithi, lingabalwa. Amafomula okubala ukugeleza kwe-volumetric eziteshini abalulekile ekuqondeni nasekuphatheni ukugeleza kwamanzi ezinhlobonhlobo zezicelo zobunjiniyela kanye nezemvelo.

Ifomula yokubala izinga lokugeleza kwevolumu ngokusebenzisa i-weir isekelwe ezimisweni ze-equation kaBernoulli, ehlobanisa ingcindezi, ijubane kanye nokuphakama koketshezi ezindaweni ezahlukene eceleni komugqa oqondile. Kuma-weirs, izinga lokugeleza e-crest lingahlotshaniswa nokuphakama kwamanzi ngaphezu kwe-crest, okuvumela izinga lokugeleza kwevolumu ukubala.

Izinga lokugeleza kwevolumu echibini libalwa kanje:

Q = C * L * H^(3/2)

Kuphi:
Q = izinga lokugeleza kwevolumu (amamitha ama-cubic ngomzuzwana)
C = i-coefficient yokukhipha i-weir
L = ubude besiqu sendlu
H = ukuphakama kwamanzi ngaphezu kwe-weir crest

I-coefficient yokukhipha amanzi e-weir (C) iyi-coefficient engenakulinganiswa echaza ukuma, usayizi kanye nezici zokugeleza kwe-weir. Inqunywa ngokuhlola futhi iyahlukahluka kuye ngohlobo lwe-weir kanye nezimo zokugeleza. Ubude be-weir crest (L) kanye nokuphakama kwamanzi ngaphezu kwe-weir crest (H) yizilinganiso ezibonakalayo ezingalinganiswa endaweni.

Ukuze usebenzise le fomula, amanani ka-C, L, kanye no-H kumele anqunywe ngokulinganisa noma ngokubala. Uma la manani eseyaziwa, izinga lokugeleza kwevolumu echibini lingabalwa kusetshenziswa le fomula. Kubalulekile ukuqaphela ukuthi le fomula ithatha ukugeleza kwamanzi okuzinzile, okufanayo emphethweni we-chibi futhi ayinaki noma yikuphi ukulahleka kwamandla ngenxa yokuxokozela noma ukungqubuzana.

Ukuqonda indlela yokubala ukugeleza kwevolumu ngokusebenzisa ama-weirs kubalulekile konjiniyela, ososayensi be-hydrologists, kanye nososayensi bezemvelo abahilelekile ekuphathweni kwemithombo yamanzi, ekulawulweni kwezikhukhula, kanye nobunjiniyela be-hydraulic. Ngokulinganisa nangokunembile nokubala ukugeleza kwamanzi ngokusebenzisa ama-weirs, izinqumo ezinolwazi zingenziwa mayelana nokwabiwa kwamanzi, ukubikezela izikhukhula kanye nokuhlolwa komthelela emvelweni.

Ngamafuphi, amafomula okubala ukugeleza kwevolumu ngokusebenzisa ama-weirs ahlinzeka ngethuluzi eliyisisekelo lokulinganisa ukugeleza kwamanzi eziteshini ezivulekile. Ngokubheka i-coefficient yokukhipha amanzi e-weir, ubude be-weir crest, kanye nokuphakama kwamanzi ngaphezu kwe-weir crest, izinga lokugeleza kwevolumu linganqunywa ngokunemba okuphezulu. Ukwakheka kudlala indima ebalulekile ekusetshenzisweni okuhlukahlukene kobunjiniyela kanye nemvelo, okufaka isandla ekuphathweni okusimeme kwemithombo yamanzi kanye nokuvikelwa kwezindawo zemvelo.
