Kuvharika kwemvura hakuwanzoitika nekuda kwechinhu chimwe chete. Ongororo dzemumunda munzvimbo dzakasiyana siyana dzekugadzira dzinoratidza maitiro akafanana: kudyidzana pakati pemhando yekugadziriswa kwemvura uye kusawirirana kwemhando yemvura. Kana kugadziriswa kwemhepo kukatadza kusvika pahuwandu hwemvura hwaitarisirwa hwe15–17% uye tembiricha ye80–85°C, chikafu chemvura chinopinda mumvura chisina kuchena zvakakwana.
