Siqulunqe saza senza uthotho lwemilomo yemilomo yokucoca itanki yamanzi, ngokobungakanani bekhabhathi, uxinzelelo lwamanzi kunye nezinye iiparameter ukukhetha umbhobho ofanelekileyo. Ngokubanzi, kwiitanki zamanzi ezineendawo ezivulekileyo ezincinci, siyile ngokukodwa itanki yamanzi yokujikeleza yokucoca umlomo enobubanzi obuncinci. Ububanzi bayo buyi-intshi enye kuphela. Ingangena kwitanki lamanzi ngokuvuleka kungaphantsi kwe-intshi enye ubukhulu. Umbhobho uqhutywa ujikeleze uxinzelelo lolwelo, ngokulula lucoca umba welinye ilizwe oqhotyoshelwe kudonga lwangaphakathi lwetanki lamanzi.

Kwiitanki zamanzi ezineendawo ezivulekileyo ezinkulu kodwa iidayimitha ezincinci zebarrel, ezinokusetyenziswa ukucoca ityhubhu yamanzi emiselweyo. Imilomo yemilomo ilungisiwe iyonke. Iibhobho zemilomo ezipheleleyo ezifakwe kuwo wonke umzimba zitshiza iarhente yokucoca macala onke ngaxeshanye ukufezekisa umphumo wokucoca udonga lwangaphakathi lwetanki lamanzi.

Kwiitanki ezinobubanzi obukhulu, sicebisa ukuba usebenzise ityhubhu yokucoca itanki yamanzi ejikelezayo, kuba inokutshiza eyona mpembelelo ifanelekileyo yokutshiza. Le mibhobho ineempembelelo ezintle kwaye ilungele ukucoca iitanki zamanzi ububanzi. . Umbhobho wayo ujikeleza kumacala amabini e-axial ngaxeshanye, ke unokugubungela wonke umphezulu wodonga lwangaphakathi lwetanki.
