Amandla abhekisa kubungakanani bomsebenzi owenziwa yinto kwiyunithi yexesha, oko kukuthi, amandla sisixa esibonakalayo esichaza ukuba umsebenzi wenziwe ngokukhawuleza kangakanani. Umyinge womsebenzi ulungisiwe, ixesha elifutshane, likhulu ixabiso lamandla. Indlela yokufumana amandla yile: amandla = umsebenzi/ixesha. Amandla abonakalisa ubungakanani bomzimba wesantya somsebenzi. Umsebenzi owenziwe kwiyunithi yexesha ubizwa ngokuba ngamandla kwaye uchazwa nguP.
Amandla e-ultrasonic
Kwinkqubo yokuhanjiswa kwezandi zamaza, xa isandi sesandi sigqithiselwa kwindawo emileyo yasekuqaleni, amasuntswana aphakathi angcangcazela abuye naphambili kufutshane nendawo elinganayo, ebangela uxinezeleko kunye nokwanda phakathi. Inokuthi ithathelwe ingqalelo into yokuba amaza omsindo enze ukuba i-medium ifumane amandla e-vibrational kinetic kunye nokuguqulwa kwamandla anokubakho. Amandla e-acoustic afunyenwe ngumbindi ngenxa yokuphazamiseka kwezandi zamaza sisimbuku samandla e-vibration kinetic kunye noguquko olunokubakho lwamandla.
Njengoko ukusasazwa kwamaza esandi kumbindi kukhatshwa kukusasazwa kwamandla, ukuba sithatha into encinci yevolumu (dV) kwindawo yesandi, masivumele umthamo woqobo wesixhobo ube nguVo, uxinzelelo lube po, kunye noxinzelelo lube ngu-ρ0. Amandla ekinetic yesiqalelo sevolyum (dV) ngenxa yesandi sokungcangcazela kwamaza △Ek; △Ek=(ρ0 Vo)u2 /2
△I-Ek ngamandla ekinetic, J; u-u sisisantya sesuntswana, m/s; ρ0 kukuxinana okuphakathi, kg/m3; IVo ngumthamo wokuqala, m3.
Isici esibalulekileyo se-ultrasound ngamandla ayo. I-Superwave inamandla amakhulu kunamaza aqhelekileyo esandi. Esi sesinye sezizathu ezibalulekileyo zokuba kutheni i-ultrasound ingasetyenziswa ngokubanzi kwiinkalo ezininzi.
Xa amaza e-ultrasonic afikelela kwindawo ethile, iimolekyuli ze-medium vibrate ngenxa yesenzo samaza e-ultrasonic, kwaye i-vibration frequency ifana ne-frequency yamaza e-ultrasonic. Ukuphindaphinda kwentshukumo yeemolekyuli eziphakathi kugqiba isantya sokungcangcazela. Iphezulu i-frequency, isantya esikhulu. Ukongeza kubunzima be-molecule ephakathi, amandla afunyenwe yi-vibration ye-molecule ephakathi nawo alingana nesikwere sesantya sokungcangcazela se-molecule ephakathi. Ngoko ke, ukuphakama kwamaza e-ultrasonic aphezulu, amandla aphezulu afunyenwe ngama-molecule aphakathi. Ubuninzi bamaza e-ultrasonic buphezulu kakhulu kunobuxhakaxhaka bamaza omsindo aqhelekileyo, ngoko ke amaza e-ultrasonic angenza iamolekyu eziphakathi zifumane amandla amaninzi, kodwa umphumo wamaza omsindo oqhelekileyo kwiimolekyuli eziphakathi zincinci kakhulu. Ngamanye amazwi, i-ultrasound inamandla amaninzi kunamaza omsindo, kwaye inokubonelela ngamandla aneleyo kwii-molecules eziphakathi.
