Amandla esatsiba okunyusa uxinzelelo awuthandabuzeki. Enye yezinto eziphambili kuyo kukunyusa uxinzelelo. Okokuqala, kufuneka sikwenze kucace ukuba phantsi kwesantya esinye sempompo, okuncinci umbhobho wokukhupha, kokukhona uxinzelelo luphezulu. Umthwalo nawo mkhulu. Umbhobho jikelele uxinzelelwe ngale ndlela, siya kugqiba ixabiso ngokwexabiso lokumpompoza lilonke, emva koko sahlule inqanaba lokuhamba kwenani lilonke ngemilomo yemilomo yokufumana isantya sokuhamba kombhobho omnye (ewe, oku Ngaphantsi koxinzelelo oluthile), ukuba isantya sokuqukuqela somlomo sisikhulu kunenqanaba lokuhamba kompompo wamanzi, uxinzelelo lwenaliti luya kuncitshiswa okanye hayi.

Ukongeza, kwimimandla ethile yokusebenza apho uxinzelelo lwempompo lungenakwandiswa, kwaye sifuna ukufumana uxinzelelo oluphezulu lwenaliti, emva koko siyile uthotho lwemilomo ye-venturi. Umgaqo-siseko osebenzayo kukusebenzisa umthetho-siseko kaBernoulli, kwaye amazinga ahlukeneyo okuhamba aya kuvelisa umahluko kuxinzelelo. Umahluko woxinzelelo usetyenziselwa ukwazisa umoya ojikeleze umbhobho ukuze wenze ifuthe elinamandla kuneloqobo.
