Estimate the specific volume of water at temperatures ?1 = 300℃ for the following pressures: p1 = 400 kpa using : (a) Van de Waals constitutive eq. (b) Redlich Kwong constitutive eq. (c) Lee and Kesler correlation for compressibility factor (d)Ideal gas eq. (e) Thermodynamic tables. Before starting the computations, evaluate the state of water for each case, in order to justify the use of the constitutive equations for real/ideal gases. In other words, we need to know if water is a gas under these conditions, in order to do meaningful computations. Make a comment about which results are more reliable and which approximation is more accurate.

Given that
Temperature T = 300 C
Pressure P = 400 kPa
