Kuvaka Muviri
Pamusana pemakona ari mumutumbi wevharuvhu yeglobe kune huwandu hwepamusoro hwekurasikirwa kwemusoro. Kurasikirwa kwemusoro ndicho chiyero chekudzikisa mumusoro wemvura yose sezvainofamba kuburikidza nehurongwa. Kurasikirwa kwemusoro kwese kunogona kuverengerwa nekupfupisa kumusoro kwemusoro, velocity musoro uye kumanikidza musoro. Kunyange zvazvo kurasikirwa kwemusoro kusingadzivisiki mumagadzirirwo emvura, inowedzerwa nekudzivisa uye discontinuities munzira yekuyerera yakadai seS chimiro chekugadzira valve yeglobe. Muviri uye pombi dzinoyerera dzakatenderedzwa uye dzakatsetseka kupa system kuyerera pasina kugadzira mhirizhonga kana ruzha. Kuti udzivise kugadzira kurasikirwa kwekuwedzera kwekumanikidza pakumhanya kwepamusoro mapaipi anofanira kunge ari nzvimbo inogara iripo. Globe mavharuvhu anowanikwa mumhando nhatu dzemiviri mikuru (kunyangwe magadzirirwo echivanhu aripo zvakare): dhizaini yemakona, Y-yakaita, uye Z- yakaumbwa.
