For H₂O, the following parameters have been proposed for the van der Waals equation of state: a = 0.5542 Pa · m⁶/mol² and b = 3.051 × 10-⁵ m³/mol. Find the specific volume of water at the same temperatures and pressures given in Example 2-3

Example 2-3

Using the ideal gas law, estimate the specific volume of steam (in L/kg) at each of the following temperatures and pressures, and compare to the specific volume in the steam tables.

A. T = 100°C, P = 0.1 bar

B. T = 150°C, P = 1 bar

C. T = 200°C, P = 10 bar

D. T = 300°C, P = 50 bar
