In a steady flow process the mass balance requires that

  • A.the total volume entering equals the volume leaving
  • B.the density is exactly the same at inlet and outlet
  • C.the velocity is exactly the same at inlet and outlet
  • D.the total mass entering equals the total mass leaving

Answer: D

Steady state means no accumulation of mass, which fixes the mass flow rates but says nothing about volume, since density changes freely with pressure and temperature. Confusing the two is a common source of error in compressible flow.
