Qhov ceev ntawm lub tshuab ua kom lub ntsej muag nplej feem ntau yog hais txog nws cov pawg ib qho ntim ib qho, tab sis tus nqi tshwj xeeb yuav sib txawv raws tus qauv thiab tsim. For example, the Olanger 5H-30 circulating grain dryer has a total mass of 5280kg and dimensions of 5364.5mm in length, 4834mm in width, and 11522mm in height, from which its density can be calculated to be approximately 0.45kg/L.
Tsis tas li ntawd, qhov ceev ntawm lub tshuab ziab khaub ncaws nplaum kuj tseem cuam tshuam los ntawm nws cov ntaub ntawv thiab kev tsim qauv. Piv txwv li, qee lub tshuab ziab khaub ncaws yuav siv cov ntaub ntawv me me los txo cov tawv nqaij thiab tus nqi siab, thaum lub tshuab ziab khaub ncaws siab siv tau cov khoom siv hnyav kom ntseeg tau tias muaj kev ruaj khov thiab kav ntev. Yog li ntawd, tus nqi txawv tshwj xeeb yuav tsum tau txiav txim siab raws cov qauv tshwj xeeb thiab cov qauv tsim qauv.
