It can calculate the properties of up to five components in a mixture, while the full version can handle up to 20 components.
It can handle only nine predefined mixtures, while the full version can handle any user-defined mixture.
It can calculate the properties of only 45 pure fluids, while the full version can handle over 120 pure fluids.
It can calculate the properties at a single state point, while the full version can calculate tables, plots, and cycles.
It can calculate only the most common properties, such as pressure, temperature, density, enthalpy, entropy, etc., while the full version can calculate more than 60 properties.
It can calculate only the ideal gas heat capacity and ideal gas entropy reference state, while the full version can calculate various reference states.
It has a simple graphical user interface (GUI) that allows the user to enter the input data and view the output data, while the full version has a more advanced GUI that allows the user to customize the display and export the data.
It does not require installation or registration, while the full version requires both.
It is free to download and use, while the full version costs $325.00.
How to Download and Use Refprop 9 0 Portable
To download and use Refprop 9 0 Portable, follow these steps:
Go to [NIST's website] and click on the Download button next to Refprop Mini.
Save the file refpropm.exe to your computer and run it. You do not need to unzip it or install it.
A window will appear with two tabs: Pure Fluids and Mixtures. Select the tab that corresponds to your calculation.
If you select Pure Fluids, you can choose one of the 45 pure fluids from the drop-down list. If you select Mixtures, you can choose one of the nine predefined mixtures from the drop-down list, or enter your own mixture composition in mole fractions.
Enter two independent variables for your calculation, such as pressure and temperature, or density and enthalpy. You can choose the units from the drop-down lists.
Click on Calculate. The output data will appear in a table below. You can view various properties, such as density, enthalpy, entropy, viscosity, thermal conductivity, etc. You can also view some information about the fluid or mixture, such as molecular weight, critical point, acentric factor, etc.
To perform another calculation, you can change the input data or select another fluid or mixture. To exit the program, you can click on Exit or close the window.
Conclusion
Refprop 9 0 Portable is a useful tool for learning and teaching thermodynamics. It can calculate the thermodynamic and transport properties of pure fluids and mixtures at a single state point. It is easy to use and does not require installation or registration. However, it has some limitations compared to the full version of Refprop, which can handle more fluids, mixtures, properties, calculations, and features. If you need more functionality and accuracy, you may want to purchase the full version of Refprop from [NIST's website].
