To taub Siab
Lub siab yog lub zog quab yuam ntawm ib cheeb tsam, feem ntau qhia los ntawm tus qauv p=F/A. Ntawm no, 'F' sawv cev rau lub zog siv, thiab 'A' qhia txog thaj chaw nyob rau hauv kev txiav txim siab.
Chav ntsuas siab
Ntau lub tshuab ua haujlwm sib txawv los ntsuas qhov siab:
SI Unit of Pressure (International System of Units)
Pascal (Pa): Tus qauv SI chav ntsuas ntawm lub siab, suav nrog millipascal (mPa) raws li lub subunit, feem ntau yog siv rau hauv kev tshawb fawb thiab engineering daim ntawv thov rau ntsuas cov feeb siab.
1 MPa=1, 000 kPa=1, 000, 000 Pa
Imperial Units
Pounds per Square Inch (psi): Siv dav hauv Tebchaws Meskas, psi qhia txog lub siab uas tshwm sim los ntawm lub zog ntawm ib phaus-force siv rau thaj tsam ntawm ib square inch.
CGS Chav (Centimeter-Gram-Second System)
Barye (Ba): Txawm hais tias tsis tshua muaj siv niaj hnub no, barye yog ib chav tsev ntawm lub siab hauv CGS system, qhov twg 1 barye sib npaug 1 dyne ib square centimeter (dyn / cm²).
Lwm Qhov Chaw:
Atmosphere (atm): Ib chav tsev siab uas siv ntau, nrog cov qauv atmospheric siab ntawm hiav txwv theem kwv yees li 101,325 Pa lossis 1 atm.
Torr: Lub npe tom qab Evangelista Torricelli, 1 torr yog sib npaug rau 1 mmHg (millimeter ntawm mercury).
Bar: Sawv cev 100,000 Pa, 1 bar ua haujlwm raws li qhov ntsuas siab. Technical Atmosphere (ntawm): Tshwj xeeb ua haujlwm hauv qee qhov chaw, qhov twg 1 ntawm txhais tau tias yog 1 kgf / cm².
Hauv qab no yog ib daim ntawv teev npe rau kev hloov pauv ntawm cov cuab yeej siv siab no.

FAQs
Dab tsi yog qhov tseem ceeb ntawm Pascal (Pa) raws li tus qauv SI unit ntawm siab?
Pascal (Pa) yog tus qauv SI chav tsev ntawm lub siab thiab tseem ceeb vim nws cov ntsiab lus ntawm lub zog thiab cheeb tsam. Ib tug Pascal yog sib npaug rau ib tug Newton ntawm quab yuam siv tshaj ib square meter. Nws yog dav siv nyob rau hauv scientific thiab engineering ntsiab lus rau nws simplicity thiab applicability nyob rau hauv ntau yam.
