Amandla asho ukuthi ungakanani umsebenzi owenziwa yinto ngeyunithi yesikhathi, okungukuthi, amandla inani elibonakalayo elichaza ukuthi umsebenzi wenziwe ngokushesha kangakanani. Inani lomsebenzi lilungisiwe, isikhathi esifushane, inani lamandla likhulu. Indlela yokuthola amandla ithi: amandla = umsebenzi/isikhathi. Amandla akhombisa inani elibonakalayo lejubane lomsebenzi. Umsebenzi owenziwe ngeyunithi yesikhathi ubizwa ngokuthi amandla futhi uchazwa ngu-P.
Amandla e-ultrasonic
Enqubweni yokudluliswa kwegagasi lomsindo, lapho igagasi lomsindo lidluliselwa endaweni emile ekuqaleni, izinhlayiya ezimaphakathi zidlidliza ziye emuva naphambili eduze nendawo yokulingana, okubangela ukucindezelwa nokunwebeka endaweni emaphakathi. Kungacatshangwa ukuthi amagagasi omsindo avumela i-medium ukuthi ithole amandla e-kinetic okudlidliza kanye namandla okuguqula amandla. Amandla e-acoustic atholwe i-medium ngenxa yokuphazamiseka kwegagasi lomsindo isamba samandla e-kinetic wokudlidliza namandla anamandla okuguga.
Njengoba ukusabalala kwamagagasi omsindo phakathi nendawo kuhambisana nokusabalala kwamandla, uma sithatha ingxenye yevolumu encane (dV) endaweni yomsindo, ivolumu yoqobo yomsindo mayibe ngu-Vo, ingcindezi ibe ngu-po, futhi ukuminyana kube ngu-ρ0. Amandla e-kinetic wento yevolumu (dV) ngenxa yokudlidliza kwegagasi lomsindo △Ek; △Ek=(ρ0 Vo)u2 /2
△I-Ek ingamandla e-kinetic, J; u isivinini sezinhlayiyana, m/s; ρ0 ukuminyana okuphakathi, kg/m3; I-Vo iyivolumu yoqobo, i-m3.
Isici esibalulekile se-ultrasound amandla ayo. I-Superwave inamandla amakhulu kakhulu kunamaza omsindo ajwayelekile. Lesi ngesinye sezizathu ezibalulekile zokuthi kungani i-ultrasound ingasetshenziswa kabanzi emikhakheni eminingi.
Lapho amagagasi e-ultrasonic efinyelela endaweni ethile, ama-molecule e-medium vibrate ngenxa yesenzo samagagasi e-ultrasonic, futhi imvamisa yokudlidliza iyafana nemvamisa yamagagasi e-ultrasonic. Imvamisa yokudlidliza kwama-molecule aphakathi nendawo inquma isivinini sokudlidliza. Lapho imvamisa iphakeme, ijubane likhulu. Ngaphezu kwesisindo se-molecule ephakathi, amandla atholakala ngokudlidliza kwe-molecule ephakathi nawo alingana nesikwele sejubane lokudlidliza le-molecule ephakathi. Ngakho-ke, ukuphakama kwemvamisa yamagagasi e-ultrasonic, amandla aphezulu atholwe ama-molecule aphakathi. Imvamisa yamagagasi e-ultrasonic iphakeme kakhulu kunemvamisa yamagagasi omsindo avamile, ngakho-ke amagagasi e-ultrasonic angenza ama-molecule aphakathi athole amandla amaningi, kodwa umphumela wamagagasi omsindo ovamile kuma-molecule aphakathi mncane kakhulu. Ngamanye amazwi, i-ultrasound inamandla amaningi kunamagagasi omsindo, futhi inganikeza amandla anele kuma-molecule aphakathi.
