Boima ba phaephe ea tšepe bo ka hakanngoa ka ho bala bophahamo ba eona bo atisitsoeng ka bongata ba tšepe.
Bakeng sa liphaephe tsa tšepe tse chitja (ho kenyeletsoa le tse se nang moqhaka leliphaephe tsa tšepe tse qhibilihisitsoeng), boima bo balwa ka tsela e latelang:
Boima ba 'mele(kg)=×(OD)2-(OD-2×WT)2)×L×ρ
ODke bophara ba kantle ba phaephe ya tshepe ka dimetara (m);
WTke botenya ba lebota la phaephe ea tšepe ka limithara (m);
