Musono weSpiral Mapaipi Akasungirirwa nedhayamita hombe
Tsananguro yeChigadzirwa:
Mapaipi edu akasungirirwa netambo dzakatenderedzwa nesimbi inotenderera ine kabhoni shoma kana kuti simbi inotenderera nesimbi inotenderera muzvikamu zvisina chinhu zvemachubhu pakona chaiyo inonzi helix angle, inonzi forming angle. Mapaipi anosungirirwa nemaoko zvakanyatsonaka kuti agadzire chigadzirwa chakasimba uye chakavimbika. Chimwe chezvinhu zvinosiyanisa mapaipi edu akasungirirwa netambo dzakatenderedzwa nesimbi ndiko kugona kwayo kugadzirwa kubva pazvidimbu zvakatetepa zvesimbi kuti igadzire mapaipi akatenderedzwa nedhayamita yakakura.
Izvimapaipi akasungirirwa ane dhayamita hombevane mashandisirwo akasiyana-siyana, kunyanya mutambo yetsvina. Pombi yedu yakasungirirwa netambo ine musono inopa simba rakakwirira uye inodzivirira ngura, zvichiita kuti ive yakakodzera masisitimu etsvina anoda mhinduro inogara kwenguva refu uye inoshanda. Ingave iri mvura inobuda mumaguta kana kuti kushandiswa kwemvura inobuda mumaindasitiri, mapaipi edu anopa rutsigiro rwakakosha uye kugara kwenguva refu.
