What is a steady flow process?

In this process, fluid properties can change from one point to another at control volume. During this whole process, the fluid properties will remain constant at any fixed point. This process allows the transfer of matter and energy through the open system steadily. Steady flow has some characteristics that are given below: -

• In control volume, no properties of fluid changes with time
  Mcv = constant
  Ecv = constant
• The properties cannot be changed at an inlet or exit point during the whole process.
• Heat and work interactions will remain constant between a steady-flow system and its surrounding during this whole process.
