Cov txheem yuam kev yog ^S. E.( p1 ua − p2 ua ) =. 025 86 e ua yuam kev yog M. E.( p1 ua − p2 ua ) =.

Ib yam li ntawd, koj tuaj yeem nug, p1 thiab p2 yog dab tsi hauv kev txheeb cais?

Qhov kev xeem txheeb cais ntawm ob qhov kev xeem yog Z-tus nqi. Z-tus nqi yog xam raws li: Qhov twg ( p1 ua – p2 ua ) yog qhov sib txawv ntawm cov qauv piv txwv, ( P1 – P2 ) yog qhov sib txawv ntawm cov pejxeem proportions xav tias Ho yog qhov tseeb (hauv qhov piv txwv no ( P1 – P2 ) = 0).

Tsis tas li ntawd, koj ua li cas sib piv ob qho piv txwv? Yuav Ua Li Cas Sib Piv Ob Qhov Pej Xeem

1. Xam cov qauv proportions. rau txhua tus qauv.
2. Nrhiav qhov sib txawv ntawm ob qho piv txwv proportions,
3. Xam qhov piv txwv tag nrho.
4. xam tus qauv yuam kev:
5. Faib koj cov txiaj ntsig los ntawm Kauj Ruam 2 los ntawm koj cov txiaj ntsig los ntawm Kauj Ruam 4.

Ib sab saum toj no, 2 qhov kev ntsuam xyuas piv txwv yog dab tsi?

A ob proportions z- xeem tso cai rau koj los sib piv ob proportions saib seb lawv puas yog tib yam. Lub tswv yim null (H₀) rau xeem yog tus proportions yog tib yam. Lwm txoj kev xav (H₁) yog li no proportions tsis zoo ib yam.

p1 thiab p2 txhais li cas?

Qhov sib txawv ntawm lub zog induced mus rau lub twj tso kua mis thiab lub zog hydraulic qhia qhov ua tau zoo ntawm lub twj tso kua mis. P1 yog tag nrho induced hwj chim rau lub twj tso kua mis system. P2 yog lub zog los ntawm lub cev muaj zog (shaft effect). P2 yog lub nominal zog ntawm lub cev muaj zog.
