Faib tus naj npawb ntawm kVA ua los ntawm 1,000 rau hloov rau MVA . Piv txwv li, yog tias koj muaj 438 kVA ua , faib 438 los ntawm 1,000 kom tau 0.438 MVA . Multiply tus naj npawb ntawm kVA ua ua 0,001 hloov rau MVA Hauv qhov piv txwv no, muab 438 los ntawm 0.001 kom tau 0.438 MVA.
Tsuas yog li ntawd, MVA fais fab raug xam li cas?
Nrhiav tus zog Piv txwv li, "pf," ntawm lub load powered los ntawm megawatt zog kev faib system. Saib cov specifications ntawm lub load. Ib yam zog 3-theem loads yog 0.8. xam 3 theem amps, los yog "I", sivthe qauv : kuv = ( MVA x 1, 000, 000)/(Vphase x1.732).
Qhov thib ob, koj yuav suav li cas kW ntawm tam sim no? AC peb theem amps rau kilowatts xam
- P(kW) = √3 × PF × I(A) × VL-L(V) / 1000.
- kilowatt = √3 × PF × amp × volt / 1000.
- kW = √3 × PF × A × V / 1000.
- P = √3 × 0.8 × 3A × 110V / 1000 = 0.457kW.
Tsis tas li ntawd, yuav ua li cas hloov kW rau kVA?
Hwj chim Factor
- Fais fab tuag (kVA) x fais fab tuag (pf) = lub zog tiag tiag (kW)
- e.g. 100 kVA x 0.8 = 80 kW.
- Cov qauv ntawm kev hloov kW rau kVA yog:
- Lub zog tiag tiag (kW) / fais fab xwm txheej (pf) = pom lub zog (kVA)
- 1 ton = 200 BTU/min.
- 1 tuj = 12,000 BTU/h.
- 1 ton = 3.517 kW.
Puas yog 1kw sib npaug rau 1kVA?
Yog li tus nqi ntawm lub zog tiag tiag lossis watts yuav yog sib npaug rau tus nqi ntawm lub zog pom lossis VA Volt-amperes. Soif lub Circuit Court yog purely resistive 1kVA ua = 1 KW . Yuav muaj "khoom siv hluav taws xob" lossis reactive zog.

Yuav ua li cas yog rau cov ntaub ntawv nug uas yuav tsum tau kawm nyob rau hauv ib tug ua txhaum cai?
Qee yam ntawm cov ntaub ntawv nug uas raug kuaj xyuas cov ntaub ntawv pov thawj tau hais hauv qab no. • Xav. • Tshawb xyuas. • Cov Nyiaj Txiag Nyiaj Txiag. • Daim ntawv cog lus. • Cov ntawv txais nyiaj. • Tub Sab Nraud. • Kev dag ntxias. • Kev cuav. • Kev tua tus kheej. • Kev tua neeg. • Nto nta. • Cov duab latent. • Kev hloov pauv. • Watermarks. • Ink stamps
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Yuav ua li cas rau lub zog thaum nws hloov ntawm ib daim ntawv mus rau lwm qhov?
Kev hloov pauv hluav taws xob yog thaum lub zog hloov ntawm ib daim ntawv mus rau lwm qhov - zoo li hauv lub tshuab hluav taws xob uas hloov lub zog kinetic ntawm dej rau hauv hluav taws xob. Thaum lub zog tuaj yeem hloov pauv lossis hloov pauv, tag nrho lub zog tsis hloov pauv - qhov no yog hu ua kev txuag hluav taws xob
Qhov kev hloov pauv twg yuav hloov daim duab A rau hauv daim duab B?
Ob daim duab tau hais tias yuav sib haum xeeb yog tias ib tus tuaj yeem tau txais los ntawm lwm tus los ntawm ib ntu ntawm kev txhais lus, kev xav, thiab kev sib hloov. Cov duab sib xws muaj qhov loj thiab zoo tib yam. Txhawm rau hloov daim duab A rau hauv daim duab B, koj yuav tsum xav txog nws hla y-axis thiab txhais ib chav nyob rau sab laug
Yuav ua li cas hloov cov tsiaj txhu yuav tsum muaj sia nyob hauv hav zoov hav zoov?
Tsiaj adaptations Ntau tus tsiaj tau yoog raws cov xwm txheej tshwj xeeb ntawm cov hav zoov hav zoov hav zoov. Tus sloth siv camouflage thiab txav qeeb heev kom nws nyuaj rau cov neeg tua tsiaj pom. Kab laug sab liab muaj cov ceg ntev ntev thiab muaj zog los pab nws nce toj ntawm cov ntoo rainforest
