Power Plant Performance Engineering
GPCALCS™ v6.0 Standard Edition
GPCALCS v6.0 Standard Edition is a collection of MS Excel® workbooks for testing
and analyzing all types of power plant equipment, including boilers, air heaters,
heat recovery steam generators (HRSGs), steam and gas turbines, condensers, cooling
towers, feedwater heaters, pumps, fans, and compressors.
This version includes a workbook to calculate the rate of fluid flow in a pipe using
either an orifice plate, flow nozzle, or Venturi tube as the measuring device. Used
by hundreds of engineers worldwide, GPCALCS is based on years of experience testing
and troubleshooting all types of power plant machinery and equipment.
See all that GPCALCS has to offer.
GPCALCS v6.0 Standard Edition includes:
Each Microsoft Excel workbook is organized for convenient data entry and report
generation. Using these workbooks, the experienced performance engineer can quickly
and accurately calculate equipment efficiencies consistent with industry methodology.
Each workbook includes blank worksheets for your own use (test averaging, DDE links,
custom reports, etc.). The following performance workbooks are provided:
- Boiler/air heater (coal) performance
- Boiler/air heater (oil/gas) performance
- Compressor performance
- Condenser performance
- Controlled extraction turbine performance
- Cooling tower performance
- Fan performance
- Feedwater heater performance

generic protocols are provided in Microsoft Word® format and can become the
basis of a comprehensive test program. Test protocols are provided for:
- Air heater
- Boiler
- Boiler feed pump
- Boiler feed pump/turbine set
- Compressor
- Cooling tower
- Feedwater heater
- Gas turbine generator
- HRSG
- Motor driven pump
- Steam surface condenser

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 the ideal gas, Peng-Robinson (PR), Benedict-Webb-Rubin
(BWR), Starling modification of BWR (BWRS), and the Soave modification of Redlich-Kwong
(RKS).

GPSteam—also available as a stand-alone product —provides
a convenient means of obtaining thermodynamic properties of water and steam (English
or metric) over a wide range of pressures and temperatures.

GPCALCS library functions are provided in Excel to return the thermodynamic properties
of gas turbine exhaust gas, boiler flue gas, or moist air at or near atmospheric
pressure.

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 Strategies units
conversion utility. The Excel add-in eliminates the need to manually search through
unit conversion tables.

In addition, a GP Strategies handy reference library workbook contains the following commonly
used reference materials, displayed as a set of worksheets:
- Periodic table of elements
- Properties of commercial pipe
- Typical coal/fuel oil/natural gas analyses
- HHV to LHV conversion
- Gas properties data (over 200 gases)
- Psychometric calculator
- Engineering unit conversion utility
- GPSteam library function
