Air Flex
Air Flex is an easy to use PC based Windows program that accurately calculates air compressor performance including flow rates based on orifice or annubar data, and state point data for various conditions.

Program features include:
Compressor Estimation – Input flow rate, inlet conditions, & discharge pressure, Air Flex calculates inlet and discharge volume flow, adiabatic head, discharge temperature, and gas power.
Compressor Test Data – Input field or factory test data, Air Flex calculates overall compressor performance including flow rates, power, and efficiency. Note – this option can also be used to verify compressor performance in new proposals.
State Point Calculation – Input a pressure and temperature, Air Flex calculates, specific volume, sonic velocity, Cp , K value, and dynamic viscosity.
A detailed summary printout is available which includes pressure, temperature, specific volume, sonic velocity, Cp , K value, and dynamic viscosity for: state points, compressor performance calculations and field test results.
The units of measurement may be varied for any item. All of the commonly used units (e. g. psia, Bar a, kg/cm2 a, etc.) are available.
Pull down windows are used for ease of program operation.
Gas Flex
A BWR Gas Properties Program for Gas Compressor Performance
Gas Flex is an easy to use PC based Windows program that uses Benedict-Webb-Rubin (BWR) equations of state for accurate compressor performance analysis.

Program features include:
State Point Calculation – Input a pressure and temperature, Gas Flex calculates enthalpy, entropy, saturation point, specific volume, sonic velocity, Cp , K value, and dynamic viscosity.
Saturation Point Calculation – Input a pressure or temperature, Gas Flex calculates the corresponding saturation temperature or pressure.
Compressor Estimation – Input flow rate, inlet conditions, & discharge pressure, Gas Flex calculates inlet and discharge volume flow, polytropic head, discharge temperature, and gas power for multi-section compressors including sideloads.
Compressor Test Data – Input field or factory test data, Gas Flex calculates overall compressor performance including flow rates, power, and efficiency. Note – this option can also be used to verify compressor performance in new proposals.
Detailed Printout – includes all relevant pressures, temperatures, enthalpies, specific volume, performance calculations and field test results.
Control of Units – for any input or output item. All of the commonly used units (e. g. psia, Bar a, kg/cm2 a, etc.) are available.
Pull Down Windows are used for ease of program operation.
Steam Flex
Steam Flex is a program based on Keenan & Keyes steam tables. Various steam properties can be calculated by the user.

Program features:
State Points: Steam state points can be calculated given a pressure and any of the following: temperature, entropy, enthalpy, and moisture.
Steam Rates: Theoretical steam rates can be calculated given inlet and exhaust pressures, plus inlet temperature, inlet enthalpy, inlet entropy, or inlet moisture.
Estimations: “”Straight through”” steam turbines can be estimated given power or inlet steam flow, speed, efficiency, inlet and exhaust pressures, plus inlet temperature, inlet enthalpy, inlet entropy, or inlet moisture. A feature allows the estimation of blade heights when disk base diameters are given.
Extractions: Extraction or induction steam turbines can be estimated similar to the straight through type.
Field Test: Turbine efficiency can be evaluated based on Field operating data.
Detailed print outs are available with each program function.
Full control of the input and output units is available. All normally used English system and metric system units are user selectable.
