Section Summary
- Siab yog lub zog ib chav tsev perpendicular cheeb tsam uas lub zog siv. Hauv daim ntawv sib npaug, lub siab txhais tau tias yog. P=FA P=F A.
- The SI unit of pressure is pascal and 1 Pa=1 N/m2 1 Pa=1 N/m 2.
Yuav ua li cas yog tus qauv siv los xam qhov siab?
Nias thiab quab yuam muaj feem cuam tshuam, thiab yog li koj tuaj yeem suav ib qho yog tias koj paub lwm tus los ntawm kev siv physics equation, P=F / A . Vim hais tias lub siab yog quab yuam muab faib los ntawm cheeb tsam, nws meter-kilogram-thib ob (MKS) units yog newtons ib square meter, los yog N/m2.
Koj ntsuas pascal li cas?
Ib Pascal unit yog txhais, nyob rau hauv lub hauv paus units, raws li 1 kilogram ib meter thib ob squared (1kg/ms2) los yog 1 newton ib meter squared (1N / m 2). Nyob rau hauv layman cov ntsiab lus, nws ntsuas lub siab siv los ntawm ib tug newton ntawm quab yuam ua ntawm lub kaum sab xis ntawm ib cheeb tsam ntawm ib square meter.
Qhov txawv ntawm PSI thiab pascal yog dab tsi?
Lub hauv paus ntawm lub siab yog lub pascal, txhais tau hais tias lub siab tawm los ntawm ib lub zog ntawm ib tug newton perpendicularly rau thaj tsam ntawm ib square meter. … 1 PSI yog kwv yees sib npaug rau 6895 Pa.
SI unit of pascal yog dab tsi?
A pascal yog SI-los ntawm chav ntsuas ntsuas rau siab . Lub pascal yog ib tug newton (ib tug SI-derived unit nws tus kheej) ib square meter. Lub Rooj Sab Laj General ntawm Qhov hnyav thiab ntsuas tau hu ua chav tsevTom qab Pascal xyoo 1971 ntawm nws 14th lub rooj sib tham.
