Steampak computes the thermodynamic and transport properties of steam and water to accuracies compatible with the International Steam Tables. Steampak also offers a powerful process calculator.

The main features of the software are:

• Vapor pressure, specific volume, specific heats, enthalpy, entropy, latent heat, conductivity and viscosity
• All properties for liquid and vapor phases versus temperature and pressure, saturated or unsaturated conditions
• Calculation of adiabatic flash, isentropic and non-isentropic processes
• US or Metric units
