Steady Flow Process
A steady flow process is a thermodynamic process in which the properties of a fluid do not change with time at any point within the system. This means the mass, energy and momentum of the fluid remain constant during its passage through the system.
Properties of Steady Flow Process
1. Rate of flow of mass energy - constant
In a steady flow process, the rate of flow of mass energy across the control surface is constant. This means that the mass of the fluid that enters the system must be equal to the mass of the fluid that leaves the system. Similarly, the energy of the fluid that enters the system must be equal to the energy of the fluid that leaves the system.
2. Thermodynamic properties vary along space as well as time coordinates
Thermodynamic properties, such as pressure, temperature, density, and velocity, can vary along space as well as time coordinates in a steady flow process. This means that the properties of the fluid can change as it moves through the system.
3. Thermodynamic properties have a fixed value
In a steady flow process, any thermodynamic property will have a fixed value at a particular location and will not alter with time. This means that the properties of the fluid at a particular location in the system will remain constant throughout the duration of the process.
Conclusion
Hence, option B is correct as both statements 1 and 3 are true. In a steady flow process, the rate of flow of mass energy across the control surface is constant and any thermodynamic property will have a fixed value at a particular location and will not alter with time. However, statement 2 is incorrect as thermodynamic properties can vary along space as well as time coordinates.
