Ukulinganisa okungenasisindo nokuqinisekisa ukudluliswa okunembile kwamanani okugeleza kwedatha

Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

Ungakhetha igama elingukhiye elilodwa noma amaningana ngezansi ukuze uthole ulwazi olufanele. Isisindo esingenasisindo singachofozwa ngokushesha “Buyisela izinto” Sesha wonke amaphazili. Q=Sv=njalo.

(I-S yindawo ephelele yesigaba, i-v yijubane lamanzi) (I-Q=AV isetshenziswa kuma-hydrodynamics), futhi ibhizinisi liyi-cubic ngomzuzwana. Ukulinganiswa okunembile kokugeleza okuphelele kwemishini yoketshezi endaweni ethile ephephile ngokuvamile kubizwa ngokuthi imitha yokugeleza. Imishini yoketshezi yokulinganisa ukugeleza iyahlukahluka. Isibonelo, izinhloso zokulinganisa ezinembile zifaka phakathi igesi, uketshezi, kanye nemishini yoketshezi exubile; izinga lokushisa, ingcindezi yokusebenza, kanye nokugeleza okuphelele kwemishini yoketshezi kuhlukile kakhulu, futhi ukunemba kokulinganisa okunembile okucacisiwe akwanele. okufanayo.

Ngakho-ke, umsebenzi wansuku zonke wokulinganisa ukugeleza uwukucwaninga ngokwesayensi izindlela ezahlukene zokulinganisa ezihlobene ngokwenhloso yokulinganisa enembile, uhlobo lwemishini yoketshezi okufanele ilinganiswe, isimo sokugeleza, indawo yokulinganisa enembile kanye nezinye izindinganiso zokulinganisa ezinembile, kanye nokuqinisekisa ukudluliswa okuphelele kwamanani okugeleza. Inani lama-cubes umfula udlula endaweni ethile ngomzuzwana owodwa. Ngokuvamile, lapho kufinyelelwa kakhulu phakathi naphansi, kulapho ukugeleza okuphelele kuba kukhulu, ngakho-ke lapho kuhlonzwa isiqondiso somfula kumephu, ngokuvamile kuba mncane kuya ebanzi.

Ukugeleza okuphelele komfula kubhekisela ekugelezeni kwamanzi kwesigaba esithile esiwela umfula ngesikhathi seyunithi, futhi ngokuvamile kuvezwa ngama-cubic metres ngomzuzwana. Ukugeleza okuphelele kungabuye kuvezwe ngokugeleza kwamanzi okuphelele kwenyanga, isizini, kanye nonyaka. Ngokombono we-hydrology, ukugeleza okuphelele kufanele kube: ngokuya ngekhwalithi yamanzi yesigaba esithile esiwela umfula ngesikhathi seyunithi, ibhizinisi elivamile liyi-cubic ngomzuzwana, futhi lisetshenziswa kakhulu ukukala ukungena nokuphuma kwesigaba esiwela umfula echibini emifuleni kanye nokungabi nesisindo. Ukulinganisa, indlela yokulinganisa yokugeleza okuphelele, ngokombono wesiteshi samanzi, ingahlukaniswa ibe yindlela ye-buoy, indlela ye-flowmeter engenasisindo, indlela ye-ultrasonic, njll. Indlela ye-flowmeter ilinganisa ukunemba.

Ifomula yokubala ukugeleza kwepayipi ibala ipayipi elaziwayo elinobubanzi obungu-12mm, ububanzi obungu-14mm, kanye nokubekezelelana okunobukhulu obungu-13mm ububanzi, kanti ukuphuma kwamanzi kwekhoyili yefeni kutholakala ngokulinganisa okungenasisindo. Ingcindezi yokusebenza ingcindezi yokusebenza yokuphakelwa kwamanzi emadolobheni. Ukubalwa kwefomula yokubala ukugeleza kwepayipi 1: 1/4∏×Imitha yesikwele yobubanzi bepayipi (iyunithi ye-mm iguqulwa ibe yiyunithi yemitha)×Ukugeleza kwamanzi kwentuthuko yezomnotho (1.1m/s yamapayipi angaphansi kwe-DN300 kanye no-1.5m/s wamapayipi angaphezu kwe-DN300) empeleni kubalwa ngamafomula amabili afanayo, izincazelo kuphela ezihlukile.

Ngaphezu kwalokho, ukuphuma kwamanzi nakho kuhlobene eduze nomfutho, kodwa manje abantu sebengakwazi okungenani ukulinganisa ukuphuma kwamanzi okulinganiselwe. Ngenxa yokuthi udonga lwepayipi lensimbi luncane kakhulu, ububanzi bepayipi bufana nobubanzi obujwayelekile bepayipi, ngakho-ke inani elimaphakathi lobubanzi bepayipi kanye nobubanzi obujwayelekile bepayipi kuthathwa njengobubanzi bepayipi.
