Determine the thermodynamic properties of water at 250 bar and 600ºC using the RK equation of state. Assume that cp,o = 28.85 + 0.01206 T + 1.002 × 105/T2 kJ kmole–1 K–1, hfg,ref = 2501.3 kJ kg–1, Pc = 220.9 bar, and Tc = 647.3 K. The reference conditions are those for the saturated liquid at its triple point (i.e., 273.15 K and 0.006113 bar). The molecular weight of water is 18.02 kg kmole–1.
