Ni ubuhe buryo bwihariye bwo kubara kwaguka kwinshi ($ D_ {ext} $) yisoko yumuraba munsi yo gutandukana cyane?

Amasoko y'umuhengeri yaguka cyane iyo yugarijwe kuko uburebure bwa arc bwumuraba buguma burigihe mugihe uburebure bwumuraba bugabanuka. Umurambararo wagutse hanze $ D_ {ext} $ ubarwa ukoresheje formula $ D_ {ext} = \ sqrt {D ^ 2 + (0.6 \ cdot N ^ 2 \ cdot (h ^ 2 - h_1 ^ 2))} $ aho $ D $ ni diameter igereranya, $ N $ ni uburebure bw’ubusa kuri buri muhengeri, kandi $ h_1 $ ni. Mubishobora kwihanganira cyane, nkibiboneka mu mashanyarazi ya hydraulic, niba itandukaniro riri hagati yisoko ya OD na bore ridahagije, isoko izahambira, bigatuma ubwiyongere butunguranye, bwiyongera bwikigereranyo cyimpeshyi kandi bishobora gutera urukuta rwamazu.
