A)
Interpretation:
Change in volume of the system at given pressure and temperature.
Concept introduction:
Thermodynamic property tables is provide the data about pressure, temperature, , specific enthalpy and entropy and specific volume at particular saturation pressure or saturation temperature or both are combined in superheat condition.
The change in volume
Here, the mass of steam is M, volume of the final state is
A)
Explanation of Solution
Refer the Appendix A-3, “Superheated steam table”, obtain the following properties of the steam at initial pressure and temperature as
The specific volume for initial state is
Refer the Appendix A-3, “Superheated steam table”, obtain the following properties of the steam at final pressure and temperature as
The specific volume for final state is
Calculate the change in volume
Here, the mass of steam is M.
Substitute 50 kg for M,
Here, negative sign indicates that the volume is leaving the system.
Thus, the change in volume

B)
Explanation of Solution
Refer the Appendix A-4, “Compressed Liquid table”, obtain the following properties of the steam at initial pressure and temperature as
The volume at the initial state is
Refer the Appendix A-4, “Compressed Liquid table”, obtain the following properties of the steam at final pressure and temperature as
The volume at the final state is
Calculate the change in volume
Substitute 100 kg for M,
Thus, the change in volume
