ZVINHU ZVINHU
– 3.3 Kuwanda kweThermal Coefficient
- Kusapisa zvakanyanya kana paine makemikarikugadzikana
–Inodzivirira kukwenya kwakanyanya, isingapindi mvura uye inodzivirira murazvo
–Kutsetseka kwakakwana uye kutsvedzerera
–Vimbiso yezuva rekutumira panguva yakakodzera
–Kubvunzana kwemunhu mumwe nemumwe uye nhungamiro yehunyanzvi
–Chimiro, saizi, finsh & dhizaini zvinogona kugadziriswa sekukumbira

Chii chinonzi girazi rekuchengetedza?
Girazi rakanyoroveswa kana kuti rakaomeswa imhando yegirazi rekuchengetedza rinogadziriswa nekurapwa kwekupisa kana kemikari kunodzorwa kuti riwedzere
simba rayo kana tichienzanisa negirazi remazuva ose.
Kudziisa kunoita kuti nzvimbo dzekunze dzive dzakamanikana uye mukati muve nepfungwa dzakasimba.
