Umthetho kaPascal kunye neNkqubo yeHydraulic
Ingcaciso elula yoMthetho kaPascal
UMthetho kaPascal wenza isiseko sayo yonke inkqubo yoxinzelelo lwamanzi. Lo mthetho uthi xa umntu efaka uxinzelelo kulwelo oluvaliweyo, uxinzelelo lunwenwela ngokulinganayo kuwo onke amacala. Uxinzelelo alwenzi buthathaka okanye lutshintshe njengoko luhamba kulwelo. Oku kuthetha ukuba amandla asetyenziswa kwindawo enye kwinkqubo angenza isiphumo esilinganayo kwenye indawo, nokuba iimilo okanye ubukhulu bezikhongozeli bahlukile.
Izazinzulu ziye zavavanya uMthetho kaPascal ngokusebenzisa imifuniselo emininzi. Omnye umboniso odumileyo yiPascal's Barel Experiment. Kolu lingelo, umntu ugalela amanzi kumbhobho omde omxinwa odityaniswe kumphanda ozaliswe ngamanzi. Nokuba umlinganiselo omncinci wamanzi kumbhobho udala uxinzelelo olwaneleyo lokugqabhuka umbhobho. Oku kubonisa ukuba uxinzelelo olufakwe phezulu luhamba ngokulinganayo kulo lonke ulwelo, kungakhathaliseki ukumila okanye ubungakanani besikhongozeli.
| Uvavanyo/Umboniso | Inkcazo | Inkalo yoQinisekiso |
|---|---|---|
| Uvavanyo lwe-Barel kaPascal | Uxinzelelo olufakwe kwindawo enye kulwelo luhanjiswa ngokulinganayo, lugqabhuke umphanda. | Iqinisekisa ukuhanjiswa koxinzelelo olulinganayo kulwelo olumileyo, oluxhasa uMthetho kaPascal. |
| Iinkqubo zeHydraulic (ijekhi, iilifti, iziqhoboshi) | Amandla amancinci kwipiston encinci enza uxinzelelo olulinganayo, okukhokelela kumandla amakhulu okukhutshwa. | Ibonisa ukuhanjiswa koxinzelelo kunye nokunyanzela ukuphindaphinda kwizixhobo zehlabathi lokwenyani. |
Ifomula yemathematika yoMthetho kaPascal yile:
P = F / Aapho u-P emele uxinzelelo, u-F emele amandla, kunye no-A emele indawo. Ukuba umntu ufaka amandla kwipiston encinci, uxinzelelo olwenziweyo luyafana kulo lonke ulwelo. Xa olu xinzelelo lufikelela kwipiston enkulu, amandla ayanda ngenxa yokuba indawo inkulu. Lo mgaqo uvumela inkqubo ye-hydraulic ukuba iphindaphinde amandla kwaye yenze imisebenzi enzima ngomzamo omncinci.
Yonke imihla Umzekelo woMthetho kaPascal
Abantu badibana noMthetho kaPascal kubomi bemihla ngemihla, rhoqo bengawuqondi. Umzekelo oqhelekileyo yi-hydraulic car jack. Xa umkhandi etyhala phantsi kwi-lever encinci, amandla ahamba nge-hydraulic fluid kwaye aphakamise imoto enzima. Uxinzelelo olwenziwa ngamandla amancinci amancinci asasazeka ngokulinganayo nge-fluid, evumela i-piston enkulu ukuba iphakamise imoto ngokukhululeka.
Eminye imizekelo ibandakanya:

|---|---|---|
| Ifomula yoxinzelelo | Uxinzelelo (P) lunyanzeliso (F) lwahlulwe ngendawo (A): P = F / A | - |
| Umthetho kaPascal kwi-hydraulics | Uxinzelelo luhanjiswa aluncitshiswanga: P1 = P2, ngoko F1/A1 = F2/A2 | Ukuba F1 = 100 N kwipiston enendawo A1, kunye A2 = 5 × A1, ngoko F2 = 500 N |
| Nyanzelela ukubala | Uhlengahlengiso kuMthetho kaPascal: F2 = (A2 / A1) × F1 | I-Master cylinder force F1 = 500 N, iidayamitha zinikiweyo, ubale i-F2 yeesilinda zamakhoboka |
| Ubalo lwendawo | Indawo ukusuka kwidamitha: A = π(d/2)^2 | I-master cylinder diameter = 0.500 cm, i-cylinder yekhoboka ububanzi = 2.50 cm |
| Umzekelo we-Hydraulic brake | Nyanzelela ukuphindaphinda ngokwahlukana kwendawo yepiston | Amandla okufaka i-100 N anyuswe ukuya kuma-500 N kwi-master cylinder, emva koko aphinda-phinda-phinda-phinda kwiisilinda zamakhoboka. |
Umzobo olula we-hydraulic press udla ngokubonisa ipiston encinci exhunywe ngombhobho kwipiston enkulu. Xa umntu etyhala kwipiston encinci, uxinzelelo luhamba kulwelo kwaye lutyhale ipiston enkulu. Lo mboniso unceda abantu ukuba baqonde indlela ukuhanjiswa koxinzelelo kunye nokunyanzeliswa kokuphindaphinda kusebenza kwi-hydraulic system.
