Neglecting changes in potential and kinetic energies, the shaft work during a steady flow process is given by
Work in steady flow process = 
Work in non-flow process = 
Consider the following statements about steady flow process:
1. The rate of flow of mass energy across the control surface are constant.
2. Thermodynamic properties vary along space as well as time coordinates.
3. Any thermodynamic property will have a fixed value at a particular location and will not alter with time.
Which of the above are correct?
1. The rate of flow of mass energy across the control surface are constant.
2. Thermodynamic properties vary along space as well as time coordinates.
3. Any thermodynamic property will have a fixed value at a particular location and will not alter with time.
Thermodynamic properties may vary along space coordinates but do not vary with time.
