| Abstract | ||
| The main aim of this work is to establish an empirical formula for calculation the enthalpy and internal energy of saturated steam. The use of this formula reflects a good result under saturated steam conditions. In order to obtain this reliable model for calculating these thermodynamic prosperities, a formula is established by nonlinear regression based on experimental data collection, after a thorough survey of literatures. Application of the proposed formula shows that, the average percentage error between the results obtained by this equation and the experimental data, is about (0.58%) for internal energy, and for enthalpy is about (0.64%), for 71 data points at each case. | ||
