ʻO nā paipu kila me ke anawaena o waho ʻoi aku ka nui ma mua o 22 mm a hiki i 400 mm, a ʻo ka mānoanoa o ka pā ma mua o 10 mm pono e hana i ka hoʻāʻo palahalaha. Ma hope o ka palahalaha ʻana o nā laʻana

Hoʻāʻo kulou

ʻO nā paipu kila me ke anawaena o waho ʻaʻole i ʻoi aku ma mua o 22 mm pono e hoʻokō i ka hoʻāʻo ʻana. He 90o ka huina piko. ʻO ka radius kulou he 6 mau manawa ke anawaena o waho o ka paipu kila.
