Xagee: F waa xoogga centrifugal ee dareeraha birta ah; m waa cufnaanta dareeraha birta; it is the rotating angular velocity of the cast. As with the gravity acceleration in the gravitational field, the metal liquid will have a centrifugal acceleration in the rotating centrifugal force field.3.2 Composition segregation For centrifugal casting of 42 CrMo ring casting, the redistribution of the solute atoms will occur with the solidification temperature and the original composition of the solid wajiga iyo wajiga dareeraha {{3} ee sidaas awgeed, waxay u horseedaa isbadal ba'an oo ka kooban isku-darka kala-sooca {{4 {4} Marka loo eego isleegyada kala-sooca macroscopic-ka ah ee qulqulka qulqulka ah iyo xawaaraha lagu qaboojiyo
