Baaritaanka Hydrostatic
Dherer kasta oo tuubo ah waa in uu soo-saaruhu ku tijaabiyaa cadaadiska hydrostatic kaas oo ka soo saari doona gidaarka tuubada cadaadis aan ka yarayn 60% ee awoodda wax-soosaarka ugu yar ee heerkulka qolka.Cadaadiska waxaa lagu go'aamin doonaa isla'egta soo socota:
P=2St/D
Kala duwanaanshaha la ogol yahay ee Miisaanka iyo Cabirka
Dherer kasta oo tuubo ah waa in si gooni ah loo miisaamaa oo miisaankeedu waa in aanu ka duwanayn in ka badan 10% ama 5.5% marka la eego miisaankeeda aragtiyeed, iyada oo la xisaabinayo iyada oo la isticmaalayo dhererkeeda iyo miisaankeeda dhererka halbeeg kasta.
Dhexroorka dibadda waa in aanu ka duwanayn in ka badan ±1% dhexroorka dibadda ee magac ahaan la cayimay.
Dhumucdiisuna waxay tahay waa in aanay ka badnayn 12.5% oo hoos timaada dhumucda gidaarka ee la cayimay.
Dhererka
Dhererka kali ah ee random: 16 ilaa 25ft (4.88 ilaa 7.62m)
Dherer labajibaaran oo random ah: in ka badan 25ft ilaa 35ft(7.62 ilaa 10.67m)
Dhererka lebbiska: kala duwanaanshaha la oggol yahay ± 1in
Dhammaad
Tuulooyinka tuubooyinka waa in lagu gogladaa cidhifyo cad, oo darafyada cidhifyada waa in laga saaraa
Marka dhamaadka dhuumaha lagu tilmaamay inuu yahay bevel uu dhamaado, xagalku waa inuu ahaadaa 30 ilaa 35 digrii
