Hydrostatic Kev Ntsuam Xyuas
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum raug sim los ntawm cov khw mus rau lub tshuab cua hydostatic Lub siab yuav tsum txiav txim siab los ntawm kab sib luag hauv qab no:
P = 2st / d
Kev tso cai sib txawv hauv qhov hnyav thiab qhov ntev
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau ua kom muaj nyias thiab nws qhov hnyav yuav tsis sib txawv ntau dua 10% dhau los yog 5.5% raws li nws qhov ntev thiab siv qhov hnyav thiab nws qhov hnyav rau ib ntu ntev
