Thermo Utilities v3.5, MS Excel Add-ins

Thermo Utilities v3.5 is a software package developed for engineers and scientists who wish to design, analyze or optimize power plants, air conditioning systems and other chemical processes. 

Thermo Utilities offers a large number of functions for calculating the properties of water, steam, air, flue gases and other fluids. The functions used for steam and water properties are based on a set of equations accepted by the members of the Sixth International Conference on the Properties of Steam. The sets of equations are also known as "IFC Formulation for Industrial Use". Thermo Utilities calculates the properties of dry air, moist air, exhaust and flue gases by using equations accepted by ASHRAE and CIBSE (Chartered Institute of Building Services Engineers). Lee-Kesler method used in this package can be applied to a large number of chemicals for estimating thermodynamic properties. The database accompanied with this package for use with Lee-Kesler method supports more than 450 chemicals. The package also offers a large number of inverse functions which are useful for applied thermodynamics calculations. The features are: 

- Support for VBA (Visual Basic for Application) 
- User selectable units for inputs/outputs 
- Calculates enthalpy, entropy, specific volume, dryness fraction, specific heat capacity, thermal conductivity, and dynamic viscosity 
- All inverse functions, needed in applied thermodynamics applications, are provided. 
- Material database for: normal freezing point, normal boiling point, critical pressure, critical temperature, critical specific volume, critical compressibility factor, Pitzer's acentric factor, dipole moment, standard enthalpy of formation and Gibb's energy of formation. 

There is also a number of worksheets available for registered users. These worksheets cover combustion of coal, biomass and fossil fuel, compressor, condenser design, cooling with dehumidification, closed-feed heaters, gas 
turbine, mixing of two air streams, regenerative steam cycle, sensible cooling/heating process, steam turbine and steam valve/throttling process.
