Iyini inzwa yezinga lamanzi?
Inzwa yezinga lamanzi iyisisetshenziswa esikala izinga loketshezi esitsheni esingaguquki esiphezulu kakhulu noma esiphansi kakhulu. Ngokwendlela yokulinganisa izinga le-liquid, lingahlukaniswa ngezinhlobo ezimbili: uhlobo lokuxhumana kanye nohlobo olungathintana naye. Uhlobo lokufakwayo lweleveli yamanzi esilubizayo isilinganiso sokuthintana, esiguqula ubude beleveli yoketshezi lube isignali kagesi ukuze okukhiphayo. Njengamanje iwumshini wokuhambisa amanzi osetshenziswa kakhulu.
Inzwa yezinga lamanzi isebenza kanjani?
Isimiso sokusebenza senzwa yezinga lamanzi siwukuthi uma ifakwa ekujuleni okuthile oketshezini oluzolinganiswa, ingcindezi endaweni engaphambili yenzwa iguqulwa ibe yizinga lobude bezinga loketshezi. Ifomula yokubala ithi Ρ=ρ.g.H+Po, kufomula P ingcindezi endaweni ewuketshezi yenzwa, ρ ukuminyana koketshezi okufanele kukalwe, g ukusheshisa kwendawo amandla adonsela phansi, i-Po ukucindezela komkhathi endaweni ewuketshezi, futhi H ukujula lapho inzwa ewela khona oketshezini.

Inzwa yeleveli iyidivayisi eklanyelwe ukuqapha nokulinganisa amazinga oketshezi (futhi kwesinye isikhathi aqinile). Uma izinga loketshezi litholwa, inzwa iguqula idatha ezwayo ibe isignali kagesi. Izinzwa zamaleveli zisetshenziselwa kakhulu ukuqapha amadamu, amathangi kawoyela noma imifula
Ungazisebenzisa kuphi izinzwa zezinga lamanzi?
Ukusetshenziswa kwezinzwa zezinga lamanzi kufaka phakathi izinhlelo zokusebenza ezilandelayo:
1. Isilinganiso samanzi samachibi namathangi amanzi
2. Isilinganiso samanzi semifula namachibi
3. Ukulinganisa izinga lasolwandle
4. Isilinganiso sezinga le-acid-base liquid
5. Ukulinganisa izinga likawoyela amaloli kawoyela namabhokisi eposi
6. Ukulawula izinga lamanzi echibini lokubhukuda
7. Isixwayiso se-tsunami nokuqapha izinga lolwandle
8. Ukulawula izinga lamanzi ombhoshongo wokupholisa
9. Ukulawulwa kwezinga lephampu yendle
10. Ukuqapha okukude kwezinga le-liquid
