Abstract: | In the calculations relating to the thermodynamic cycle of steam power plants, the enthalpy and the entropy of saturated liquid and saturated steam (hf, hg, sf, and sg) are needed. If one uses industrial formulation IAPWS-IF97, these four parameters (hf, hg, sf, and sg ) should be determined by cumbersome numerical computations when the saturated pressure has a value between 16.529 MPa and 22.064 MPa. In this work, easy programmable equations are provided to calculate hf, hg, sf, and sg in this range of saturated pressure. |
