Answer
Nkuko isoko yumurambararo ihagarikwa kuva muburebure bwayo $ H $ kugeza murwego rwo hejuru $ H_w $, imiraba irasibangana, bigatuma hagati ya diameter $ D_m $ yaguka. Kwaguka $ \ Delta D $ birashobora kugereranywa na $ \ Delta D = \ frac {0.051 (h ^ 2 - t ^ 2) N ^ 2} {D_m} $. Niba itandukaniro riri hagati yimvura yo hanze (OD) hamwe nuburaro bwamazu bidahagije, isoko izahambira, bigatuma ubwiyongere bukabije bwikigereranyo cyimpanuka kandi bishobora guhinduka burundu. Ba injeniyeri bagomba kwerekana diameter ya bore $ D_ {bore}> OD_ {max} + \ Delta D $ kugirango barebe imikorere yimvura nkigiti cyoroshye kidafite imbogamizi ya kabiri ya radiyo.
