Uma kukhulunywa ngama-spa okubhukuda, ukuqonda izinga lokugeleza kwamanzi kubalulekile ukuze ube nesipiliyoni esihle sokubhukuda. Ake singene efomini yokubala sisebenzisa ichibi lamamitha le-FSPA 12*3.2 njengesibonelo.
Izinga lokugeleza kwamanzi endaweni yokubhukuda linqunywa ngefomula elula kodwa ephumelelayo: indawo yendawo yokubhukuda engapheli iphindaphindwa ngejubane lokugeleza elivivinyiwe bese kuba nenani lemizuzwana ngehora. Endabeni yechibi le-FSPA, indawo yokungena inobude obungu-780mm (0.78m) kanye nobubanzi obungu-370mm (0.37m). Ijubane lokugeleza elivivinyiwe lingu-2m/s.
Okokuqala, sibala indawo ye-outlet, okungu-0.78m * 0.37m = 0.2886m². Bese siphinda le ndawo ngejubane lokugeleza (2m/s) kanye nenani lemizuzwana ngehora (3600s). Ngakho-ke, 0.2886m² * 2m/s * 3600s = 2088m³/h.
Lokhu kubala kubalulekile njengoba kusinika umbono wamandla namandla omsinga wamanzi endaweni yokubhukuda. Izinga lokugeleza eliphakeme lisho umsinga onamandla, ofanelekela ukubhukuda ibanga elide noma ukuzivocavoca okunzima kakhulu. Ngezinga lokugeleza elibalwe yichibi le-FSPA, ababhukudi bangajabulela isipiliyoni sokubhukuda esiqhubekayo nesingenakuphazamiseka, njengokubhukuda olwandle olungenamkhawulo.
Ngakho-ke, ngesikhathi esizayo lapho ucabangela indawo yokubhukuda, khumbula ukubaluleka kokubala izinga lokugeleza kwamanzi ukuze uthole elifanele izidingo zakho.
