Hoʻohana ʻia ka paipu kila e hoʻoili i ka wai a me ka pauka, hoʻololi i ka wela a hana i nā ʻāpana mechanical a me nā ipu, a he ʻano kila waiwai hoʻi. ʻO ka hoʻohana ʻana i nā paipu kila no ka hana ʻana i nā grids kūkulu hale, nā pou a me nā kākoʻo mechanical hiki ke hōʻemi i ke kaumaha a mālama i ka 20-40% o ka metala, a hiki ke hoʻomaopopo i ka hana mechanized e like me ka hale hana. He aha nā ʻano paipu kila i loaʻa mau? He aha ka nui o ka paipu kila? Hoʻopuka kēia ʻatikala iā lākou i kēlā me kēia.
E puunaue i 1 iniha i 8 mau apana like; 1/8 1/4 3/8 1/2 5/8 3/47/8 iniha.
