Inā he mea hou ʻoe i ka ʻoihana paipu a i ʻole ka ʻoihana paipu alloy a i ʻole ʻoe i ka ʻoihana no nā makahiki, ʻaʻole mea hou ka huaʻōlelo "Schedule 40" iā ʻoe.ʻAʻole ia he huaʻōlelo maʻalahi, he metric kī, no laila e ʻeli hohonu a ʻike i ke kumu i kaulana ai ka Hōʻike 40!
He aha ka Papa 40
ʻO kahi paipu Hōʻike 40 he paipu me ka mānoanoa o ka paia.E ʻokoʻa ka mānoanoa o ka pā ma muli o ke anawaena o waho o ka paipu.ʻO kēia no ka mea ʻaʻole pili ka helu ma hope o ka Hōʻike i kahi mānoanoa pā kikoʻī, akā he hoʻokaʻawale.
He ala maʻalahi ke kumu no ka helu ʻana i ka helu Hōʻike i ka pilina ma waena o ka mānoanoa o ka pā o ka paipu a me ke kaomi ʻana.
Penei ke kumu:
Helu papa helu = 1000 (P/S)
Phōʻike i ke kaomi hana hoʻolālā o ka paipu, maʻamau i ka psi (paona i kēlā me kēia ʻīniha square)
Shōʻike i ke koʻikoʻi haʻahaʻa i ʻae ʻia o ka mea paipu ma ka wela hana, a ma ka psi (paona no kēlā me kēia ʻīniha square).
Hāʻawi kēia ʻano hana i kahi ʻano hana manaʻo no ka hoʻomaopopo ʻana i ka pilina ma waena o ka mānoanoa o nā paipu me nā waiwai Hōʻike like ʻole a me ke kaomi kiʻekiʻe hiki iā lākou ke pale palekana.I ka hoʻomaʻamaʻa ʻana, ua hoʻoholo mua ʻia ka waiwai Hōʻike o kahi paipu ma ka maʻamau.
