Explanation:

Steady flow process is a process where: the fluid properties can change from point to point in the control volume but remains the same at any fixed point during the whole process. A steady-flow process is characterized by the following:

  • No properties within the control volume change with time. That is mcv = constant; Ecv = constant
  • No properties change at the boundaries with time. Thus, the fluid properties at an inlet or exit will remain the same during the whole process.
  • The heat and work interactions between a steady-flow system and its surroundings do not change with time.
