khalidwe

Mavewo omwe amadziwika kuti amayenda pang'ono, monga momwe dzina lake limatanthawuza, ndi valavu yolamulira yopingasa yofalitsidwa.

Kutha kwamphamvu kwa valavu ndilolo lolozera bwino kwambiri. China zikuyimiriridwa ndi CR. Amadziwika kuti: Livali litatsegulidwa kwathunthu, pamene mphamvu ikusinthana ndi 1kg / cm2, sing'anga misa (m3 / hr) nthawi iliyonse. Madzi osagwirizana, mothandizidwa ndi chiwerengero chonse (pomwe Reynolds nambala ndi yayikulu mokwanira, re> 10 5 ya madzi; re> 5.5 × 104 pa mpweya)

Kuti:

△ p-kukakamiza kusiyana pambuyo pa Valavu (kg / cm2) υ-sing'anga (g / cm3)

Q-Media Kuyenda (m3 / h)

United States ndi mayiko ena amagwiritsa ntchito mtengo wa C kuti uwonetse mphamvu ya valavu. Ikudziwika padziko lonse lapansi, e ndi C mfundo makamaka yokhudzana ndi magetsi kugwiritsa ntchito mav. Ubale pakati pawo ndi motere:

CV = 1 .17 C CV = 10 6/2411 C = 10 6/281

Kutha kwamphamvu kwa valavu kumangotengera mawonekedwe a valavu yokha. Mukamawerengera valavu yofunikira yofunikira, iyenera kudziwitsidwa kuti malo otsika mu valavu adzakhala osiyana kwambiri pamene sing'anga ndi wosiyana kapena nyengo yoyenda ndi yosiyana.

Pankhani yotentha kwambiri, makamaka ma vicous madzimadzi komanso kukakamizidwa kwambiri, kutsimikiza kwa madzimadzi nthawi zambiri kumakhala kwa laminar kapena mikhalidwe yosakanikirana. Kutuluka kwa laminar, pali ubale wa mzere pakati pa kayendedwe ka Valive ndi kupanikizika nthawi isanakwane. Mu mkhalidwe wosakanikirana wa kutuluka kwa laminar yotsika komanso yotsekemera, ndi kuchuluka kwa nambala ya reynols, ngakhale kusintha kwa kukakamizidwa kumatha, kuchepa kwa dielect kumadutsa mu valavu ikuwonjezeka. M'mapeto athunthu, kuchuluka kwake sikusintha ndi nambala ya reynolds. Komabe, kusankha kwa valavu yaying'ono yoyendetsedwa kumangochitika ndi njira zachikhalidwe ndi njira zowerengera. Komabe, mtengo wowerengedwa umasokera kwambiri kuchokera pamtengo weniweni. Malinga ndi data, pomwe CV ili pansi pa CV = 0.01, imangogwiritsidwa ntchito ngati mndandanda wazolowera ndipo ali ndi tanthauzo lofunikira. Kuchuluka kwa malire omasulira ayenera kutsimikiza malinga ndi
