A saturated steam table is an indispensable tool for any engineer working with steam. It is quite cumbersome to calculate each time, the value and relation between various properties. So, these are experimentally determined and presented in the form of tables showing value of each property w.r.t either saturation temperature or saturation pressure. It is typically used to determine saturated steam temperature from steam pressure, or the pressure from saturated steam temperature. In addition to pressure and temperature, these tables include other related values such as specific enthalpy (h) and specific volume (v), and specific entropy (s). All the properties are vary with the change in saturation pressure and for a particular saturation pressure there is a fix value of saturation temperature. These properties are required in thermo dynamic calculations where steam is used as working medium. The value of properties of saturated steam and superheated steam are given separately. If any given pressure falls in between two values given in table then value of concerned property on this pressure may be calculated by interpolation. The column in the steam table showing properties of saturated stream are as given below: Absolute Pressure in bar ( P Saturated Temperature in °C t Specific Volume in m3/kg Specific Enthalpy in kJ/kg Specific Entropy in kJ/Kg K Water vf Steam vg Water hf Evaporation hfg Steam hg Water sf Evaporation sfg Steam sg
