O centro de massa é onde se supõe estar concentrada toda a do corpo e onde se considera estarem aplicadas todas as que nele atuam. O centro de massa move-se com a mesma do conjunto de pontos do corpo.
Um corpo pode ser representado pelo seu centro de massa, se:
• As variações da energia forem desprezáveis
• Os corpos forem ou não deformáveis
• Existir apenas movimento de , ou seja, todos os pontos se movem à mesma .

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
