Mahia te whakamātautau e whai ake nei.
Whakairihia he taumaha ki runga i te dynamometer ka tuhia te taumaha e tohuhia ana e te dynamometer. Muri iho, whakatakotoria te taumaha ki roto i te wai ka tuhia te taumaha e tohuhia ana e te dynamometer.
Whakatauritea ō inenga. He nui ake te taumaha ina kei roto i te wai, ina kore rānei i roto i te wai? He aha ai? Matapakihia ngā hua o tēnei whakamātautau me tō hoa.
Ki te tika te whakahaere i te whakamātautau, ka whakaatu ngā hua he iti ake te taumaha o te kawenga ina kei roto te kawenga i te wai. Ka pērā anō te āhua ina hikihia e koe tētahi mea i roto i te wai, ā, ka puta ki waho. Ka māmā ake te ahua o te mea i hikihia i roto i te wai i te taumaha kotahi i hikihia i waho i te wai. Ka iti ake te taumaha ina kei roto te kawenga i te wai, ka māmā ake rānei te ahua o te mea i hikihia i roto i te wai nā te kaha pōrewa e pā ana ki te mea.
Te Mārama ki te Puawai
Pupuhi Ko te kaha hua, ko te kaha katoa rānei e anga whakarunga ana e pā ana ki runga e tukuna ana e te wai ki runga i tētahi mea ina noho te mea i roto i te wai. Ko ngā wai he matū ka taea te rere, hei tauira, te hau me te wai.
Tātai Mana Pupuhi
Ina noho tētahi mea i roto i te wai, ka panaia te mea e te wai i runga ki raro, ka panaia hoki e te wai i raro ki runga.
Te kaha o te pūangi:
Ngā Mōhiohio:
(rho) = Te mātotoru o te wai (Kg/m 3 ), g = Te whakaterenga nā te kaha ā-papa (9,8 m/s 2 ), V = Te rōrahi o te mea e rumakina ana ki te wai (m 3 ), A = Te horahanga o te mata o te mea (m 2 ), h = h 2 – h 1 = Te rerekētanga o te hohonutanga o te wai i runga ake me raro i te mea e rumakina ana ki te wai (m)
He nui ake te pēhanga, te pana rānei o te wai (wai) i te hohonutanga o te h 2 i te wai (wai) i te hohonutanga o te h 1. Mā te rerekētanga o te pēhanga, te pana rānei ka puta he kaha katoa e anga ana ki runga. He rite tonu te hohonutanga o te wai (wai) ki te taha maui me te taha matau o te mea, nō reira he ōrite te kaha hua ki te kore.
