Akubuzwa ukuthi ikhono lombhobho lokwengeza ingcindezi. Elinye lamakhono alo amakhulu ukukhulisa ingcindezi. Okokuqala, kufanele sikwenze kucace ukuthi ngaphansi kwesisekelo sejubane elifanayo lempompo, lapho kuncipha ipayipi lokukhipha, ingcindezi iyanda. Umthwalo nawo mkhulu. Umbhobho ovamile ucindezelwe ngale ndlela, sizonquma inani ngokuya ngenani lokugeleza okuphelele kwepompo, bese sihlukanisa inani lokugeleza okuphelele ngenani lamabhomu ukuthola isilinganiso sokugeleza kombhobho owodwa (kunjalo, Lokhu ingaphansi kwengcindezi ethile), uma inani lokugeleza kombhobho lilikhulu kunezinga lokugeleza okuphelele kwepompo yamanzi, khona-ke ingcindezi yomjovo izoncishiswa noma cha.

Ngaphezu kwalokho, kwezinye izindawo zokusebenza lapho ingcindezi yepompo ingenakwanda khona, futhi ifuna ukuthola ingcindezi ephezulu yomjovo, lapho-ke sakha uchungechunge lwemibhobho ye-venturi. Umgomo wayo osebenzayo ukusebenzisa umgomo kaBernoulli, futhi amazinga wokugeleza ahlukile azokhiqiza umehluko wengcindezi. Umehluko wengcindezi usetshenziselwa ukwethula umoya osizungezile embhobho ukuze wenze umthelela onamandla kunowokuqala.
