Xa kufikwa kwiindawo zokudada, ukuqonda izinga lokuhamba kwamanzi kubalulekile ukuze ube namava amahle okudada. Masijonge kwifomula yokubala sisebenzisa ichibi le-FSPA 12*3.2 – meter njengomzekelo.
Izinga lokuhamba kwamanzi kwindawo yokudada limiselwa ngefomula elula kodwa esebenzayo: indawo yendawo yokudada engapheliyo iphindaphindwe ngesantya sokuhamba esivavanyiweyo uze emva koko ube nenani lemizuzwana kwiyure. Kwimeko yedama lokudada le-FSPA, indawo yokuphuma inobude obuyi-780mm (0.78m) kunye nobubanzi obuyi-370mm (0.37m). Isantya sokuhamba esivavanyiweyo yi-2m/s.
Okokuqala, sibala indawo ye-outlet, eyi-0.78m * 0.37m = 0.2886m². Emva koko, siphinda-phinda le ndawo ngesantya sokuhamba (2m/s) kunye nenani lemizuzwana kwiyure (3600s). Ngoko ke, 0.2886m² * 2m/s * 3600s = 2088m³/h.
Olu balo lubalulekile kuba lusinika umbono wamandla kunye nobukhali bomsinga wamanzi kwindawo yokudada. Isantya esiphezulu sokuhamba kwamanzi sithetha umsinga onamandla, ofanelekileyo ekuqubheni umgama omde okanye ukuzilolonga okunzima ngakumbi. Ngesantya sokuhamba kwamanzi esibaliweyo sedama le-FSPA, abaqubhi banokonwabela amava okudada aqhubekayo nangenakuphazamiseka, njengokudada elwandle olungenasiphelo.
Ngoko ke, kwixesha elizayo xa ucinga nge-swim spa, khumbula ukubaluleka kokubala isantya sokuhamba kwamanzi ukuze ufumane esifanelekileyo kwiimfuno zakho.
