Make a Z − P plot of water using data from the steam tables showing the same information as the PV graph above.

Problem 2.10: a) Use data from the steam tables to construct the PV graph of water. Show the saturated liquid, the saturated vapor, the critical point. Include the isotherms at 100 °C, 200 °C, 300 °C and 400 °C. Make two plots, one using linear axes and one in which the pressure axis is linear but the volume axis is logarithmic.

 

b) Make a − plot of water using data from the steam tables showing the same information as the PV graph above.

 

Problem 2.11: Determine whether the truncated virial equation is valid for ethane at the following states: a) 10 bar, 25 °C.

 

b) Saturated vapor at 10 bar. c) 10 bar, −35 °C.

Additional data: The boiling point of ethane at 10 bar is −29 °C.
