Chii chinonzi Schedule 40
A Schedule 40 pombi ipombi ine chaiwo madziro ukobvu.Iyo chaiyo madziro ukobvu ichasiyana zvichienderana nekunze kwedhayamita yepombi.Izvi zvinodaro nekuti iyo nhamba mushure meKurongwa hairevi zvakananga kune yakatarwa madziro ukobvu, asi panzvimbo pezvo ikamu.
Nzira yekuverenga nhamba yeChirongwa inzira yakarerutswa yekufungidzira hukama huri pakati pekukora kwemadziro epombi uye kumanikidzwa kwainoitwa.
Iyo formula ndeyotevera:
Purogiramu Nhamba = 1000 (P/S)
Pinomiririra dhizaini yekushanda kwepombi, kazhinji mupsi (mapaundi paskweya inch)
Sinomiririra kushomeka kunobvumidzwa kushushikana kwepombi zvinhu pakupisa kwekushanda, zvakare mupsi (mapaundi paskweya inch).
Iyi fomula inopa theoretical framework yekunzwisisa hukama pakati pehukobvu hwemapombi ane akasiyana Schedule values uye yakanyanya kudzvanywa yavanogona kumira zvakachengeteka.Mukuita, kukosha kweChirongwa chepombi kunotsanangurwa muchiyero.
