Qhov tshwj xeeb tshaj yog, qhov porosity ntawm pob zeb yog qhov ntsuas ntawm nws lub peev xwm tuav cov kua dej. Ua lej, nws yog qhov chaw qhib hauv pob zeb faib los ntawm tag nrho cov pob zeb ntim (khoom thiab qhov chaw). Permeability yog ib qho kev ntsuas ntawm qhov yooj yim ntawm cov dej ntws los ntawm cov khoom ntxeem tau.
Puas porosity nce nrog permeability?
Porosity=(ntim ntawm qhov hauv cov khoom) / (tag nrho ntim ntawm cov khoom). Qhov porosity ntawm tib cov khoom yog tib yam, txawm tias qhov loj me me sib txawv. Tab sis permeability yog qhov sib txawv. Nws nce raws li qhov loj me zuj zus.
Puas porosity thiab permeability inversely cuam tshuam?
Permeability yog lwm yam khoom tseem ceeb ntawm txhua yam khoom thiab yog ze ze rau qhov porosity. Permeability hais txog qhov sib txuas ntawm qhov pore rau ib leeg.
YPuas siab porosity txhais tau tias siab permeability?
Permeability yog ib qho kev ntsuas ntawm cov degree uas cov pore qhov chaw sib cuam tshuam, thiab qhov loj ntawm kev sib tshuam. Tsawg porosity feem ntau ua rau qis permeability, tab sis siab porosity tsis tas txhais tau siab permeability.
YKoj ntsuas qhov permeability thiab porosity li cas?
Porosity yog txiav txim siab los ntawm kev ua cov duab kho qhov muag thaum nws raug dej nyab los ntawm cov kua dej dyed. Permeability yog xam los ntawm ntsuas qhov siab poob thoob plaws nti rau qhov sib txawv ntawm cov dej ntws ntawm deionized (DI) cov dej txhaj rau hauv nti.
