Answer
Iyo isoko yumuraba ihagaritswe kuva muburebure bwayo ($ H_f $) yerekeza ku burebure bwakazi ($ H_w $) cyangwa uburebure bukomeye ($ H_s $), imiraba irasibangana, bigatuma diameter ya $ D_m $ yiyongera bitewe na geometrike yibice bya arc. Kwagura hafi $ Δ D $ birashobora kugereranywa ukoresheje umubano $ Δ D = 0.02 \ cdot \ frac {(H_f - H_w) ^ 2} {D_m} $. Mugihe cyo kwihanganira gukomera, kwishyiriraho imirasire ningirakamaro kugirango wirinde guhuza. Ba injeniyeri bagomba kubara 'Ntarengwa Yaguwe OD' bakoresheje $ OD_ {max} = OD_ {ubuntu} + \ sqrt {L ^ 2 + R ^ 2} - R $, aho $ L $ ari uburebure bw’umuraba naho $ R $ ni radiyo yo kugabanuka. Niba isoko idakumirwa na bore, uku kwaguka gutera impagarara za kabiri zishobora gutuma umuntu atanga umusaruro utaragera cyangwa 'gukubita' kurukuta rwa bore, bisaba ko hagabanywa OD ibanza.
