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.

Air Flex is a subprogram of Flex Live

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.


Data Analysis
Use the following Excel Worksheet for plotting the results of your analysis. The worksheet uses 5 points from the compressor manufacturers curve as a base line. The operating data is fan law corrected for comparison to the design curve.
