Txhais. Ib megapascal ( MPa ) yog qhov ntsuas ntawm qhov nrawm lub zog ntawm pob zeb. Ib MPa yog sib npaug rau ib lab pascals (Pa); Raws li ib tug pascal yog ib tug newton ntawm quab yuam ib square meter, ib tug megapascal yog ib lab newtons ib square meter.

Tom qab ntawd, ib tug kuj yuav nug, MPa lub ntsiab lus yog dab tsi?

Lub megapascal yog x1000000 ntau yam ntawm pascal unit uas yog SI unit rau siab. 1 megapascal sib npaug 1, 000, 000 pascals Feem ntau siv rau ntau qhov ntsuas siab vim nws muaj nqis ntau dua (piv txwv li 1 MPa = 10 bar), cov MPa feem ntau yog siv los piav qhia qhov siab thiab ntsuas ntawm cov tshuab hydraulic.

Ib yam li ntawd, 30 MPa pob zeb siv rau dab tsi? Siab zog Pob zeb Rau 30 MPa (nominal ntawm 28 hnub) no qhob kev sib xyaw yog tsim nyog rau kev tshem tawm cov kab teeb thiab cov slabs; nrog rau cov khoom precast xws li flagstones thiab hnyav-duty nto xws li rhiav pem teb.

Ib qho ntxiv, ntau npaum li cas yog Megapascal?

Megapascal yog ntsuas ntsuas ntsuas thiab sib npaug rau 1 000 000 quab yuam Newton ib square meter

Dab tsi yog 15 MPa qhob siv rau?

Lub zog qis ( 15 MPa ) qhob yog tsim rau cov hauv paus tsis muaj zog (ib leeg xwb); loj filling, infill qhob hauv masonry (tsuas yog nrog 13, 2-mm pob zeb). 2. Lub zog nruab nrab (25 MPa ) qhob yog qhov tsim nyog rau cov nplais tsis muaj zog, ntxiv cov nplais thiab cov hauv paus, ntxiv rau qhob hauv masonry (tsuas yog nrog 13, 2 hli pob zeb).
