GPCALCS™ Version 6.0

for $49

Student Edition

Aiming to provide students with the tools they need to succeed, GP offers the GPCALCS v6.0 Student Edition. Using this set of reference tools, students will no longer have to search through endless numbers of books. You will have a handy reference library containing the latest periodic table of elements and a psychrometric calculator, along with a unit conversion library with hundreds of automatic engineering unit conversion calculations. In addition, we include access to the 1967 and 1997 ASME Steam Property Formulations with an interactive Mollier diagram (GPSteam™ Properties Calculator) and the GPSteam Library DLL in Excel. Lastly, the student edition contains a gas and gas mixture properties calculation tool using the ideal gas, Benedict-Webb-Rubin (BWR), Starling modification of Benedict-Webb-Rubin (BWRS), Soave modification of Redlich-Kwong (RKS), and Peng-Robinson (PR) equations of state (GPGas™ Properties Calculator) and the GPGas Library DLL in Excel.

GP Handy Reference Library

GP Unit Conversion Library / Add-In

Unit conversions are provided for automatic engineering unit conversions (both English and metric) for user inputs as well as any calculated values using the GP Units Conversion Utility. The Excel add-in eliminates the need to manually search through unit conversion tables.

GPSteam Properties Calculator / Add-In

This tool provides a convenient means of obtaining thermodynamic properties of water and steam (English or metric) over a wide range of pressures and temperatures. By entering any two state conditions (P, T, h, S, Q), the program returns ten physical properties of the fluid. The calculator provides a user-selectable 'switch' to use either the 1967 or 1997 ASME Steam Property formulations. A graphical user interface also displays an active Mollier diagram and enthalpy-drop efficiency calculations for one or more expansion lines. '67 and '97 Steam Tables are provided in Excel through the GPSteam Library DLL.

GPGas Properties Calculator / Add-In

This tool calculates real gas properties of gases and gas mixtures. Given pressure, temperature, and composition, the calculator provides the following properties based on a user-selectable equation of state:

• Specific Volume
• Enthalpy
• Entropy
• Specific Heat
• Vapor Pressure
• Compressibility
• Isentropic Exponent (Ratio of Specific Heats)

Additionally, a second point can be entered and the calculator will calculate the polytropic head (work), exponent, and efficiency for a compression or expansion process. Gas property values are provided in Excel through the GPGas Library DLL. Available equations of state are Peng-Robinson (PR), Benedict-Webb-Rubin (BWR), Starling modification of BWR (BWRS), Soave modification of Redlich-Kwong (RKS), and ideal gas.
