No. Many gas systems (especially steam systems) are pressure driven, and weight or area optimization can be quickly and effectively used to optimize the system. While it may not be as effective as cost optimization, weight optimization for pipes and area optimization for ducts will frequently track cost with a minimum of effort.

SteamCalc offers two different formulations for calculating water and steam properties. The first option uses the 1997 formulations developed by the International Association for the Properties of Water and Steam (IAPWS-IF97), as presented by the ASME in their publication "ASME Steam Tables For Industrial Use". The second option uses the 1984 water and steam property formulations published by the National Bureau of Standards (NBS).

SteamCalc calculates a full range of water and steam properties, including: Pressure (including saturation), Temperature (including saturation), Density, Enthalpy, Entropy, Specific Heat, Viscosity, Bulk Modulus of Elasticity, Compressibility Factor, Prandtl Number, Sonic Velocity, Phase, and more.

SteamCalc requires two thermodynamic properties as input. The input properties can be entered in many different combinations. The properties that can be used as input include: Pressure, Temperature, Density, Specific Volume, Enthalpy, Entropy and Quality

SteamCalc can be used to easily determine saturated liquid and vapor properties. In addition, SteamCalc has the ability to calculate properties in the two-phase saturation region.

SteamCalc allows you to calculate water and steam properties for a single point, two points simultaneously, or for a range of points.

SteamCalc offers a full range of configuation options that allow you to fully control the content and form of the output values. The calculated output is displayed in a grid format. The data may be displayed in either horizontal or vertical rows in the grid. In addition, you can specify which parameters are displayed, and which are not, so only the data you wish to see is displayed. SteamCalc also allows you to specify the units used for each calculated value displayed.

SteamCalc provides the capability to copy the contents of the output grid to your computer's clipboard. From there, the values may be pasted directly into other applications, such as a spreadsheet program. In addition, SteamCalc allows you to save the results to at text file.
