Water-steam properties: Excel spreadsheet that contains the following physical properties of water and steam (both saturated and overheated): Vapor pressure, density, dynamic viscosity, specific heat at constant pressure and volume, surface tension, therma conductivity, specific enthalpy and entalphy of vaporization, entropy and free Gibbs energy. Properties have been tabulated using IAPWS-97. The properties of superheated steam are calculated up to 450°C for some pressures (others will be added later).
Air properties: Excel calculation sheet with main properties of dry air, taken with a process simulator and calculated at 1 atm and in the temperature range -50 / + 500°C. Tabulated properties are the following: Mass density, dynamic viscosity, specific heat at pressure and costant volume, thermal conductivity and Prandtl number.
