Question:

This problem is an expansion of Example 2-3. The table below lists 10 sets of conditions—five temperatures at a constant P, and five pressures at a constant T. For each T and P, find:

• The specific volume of steam, from the steam tables

• The specific volume of steam, from the ideal gas law Comment on the results. Under what circumstances does departure from ideal gas behavior increase? Temperature Pressure 5 bar 5 bar 5 bar 5 bar 5 bar 0.1 bar 1 bar 5 bar 10 bar 25 bar 200C 300C 400C 500C
