Ikizamini cya Hydrostatike
Buri burebure bwumuyoboro bugomba kugeragezwa nuwabikoze kumuvuduko wa hydrostatike uzatanga murukuta rwumuyoboro impungenge zitari munsi ya 60% yumusaruro muto wagenwe mubushyuhe bwicyumba.Umuvuduko uzagenwa nuburinganire bukurikira:
P = 2St / D.
Impinduka zemewe muburemere nubunini
Buri burebure bw'umuyoboro bugomba gupimwa ukundi kandi uburemere bwacyo ntibushobora gutandukana hejuru ya 10% hejuru ya 5.5% munsi yuburemere bwacyo, ubarwa ukoresheje uburebure bwacyo n'uburemere bwacyo muburebure.
Diameter yo hanze ntishobora gutandukana kurenza ± 1% uhereye kuri nomero yerekanwe hanze ya diameter.
Umubyimba wurukuta umwanya uwariwo wose ntushobora kurenza 12.5% munsi yubugari bwurukuta.
Uburebure
Uburebure bumwe butunguranye: 16 kugeza 25ft (4.88 kugeza 7,62m)
Uburebure bubiri bubiri: hejuru ya 25ft kugeza 35ft (7.62 kugeza 10.67m)
Uburebure bumwe: gutandukana byemewe ± 1in
Iherezo
Ibirundo by'imiyoboro bigomba kuba bifite impera zisanzwe, kandi burr ku mpera zizakurwaho
Iyo imiyoboro irangiye yerekanwe kuba bevel irangiye, inguni igomba kuba dogere 30 kugeza 35
