How to Download, Install and Use Computer-Aided Thermodynamic Tables 3 (CATT3) for Thermodynamic Problems


Computer-Aided Thermodynamic Tables 3 - CATT3




Computer-Aided Thermodynamic Tables 3 (CATT3) is a software that allows users to access and manipulate thermodynamic data of various substances, such as water, air, gases, refrigerants and psychrometric properties. CATT3 is a useful tool for engineers, students and researchers who need to perform thermodynamic calculations and analyses.




Computer-Aided Thermodynamic Tables 3 - CATT3



Introduction




What is CATT3?




CATT3 is a software developed by John Wiley & Sons, Inc. that provides electronic thermodynamic tables for different substances. CATT3 can be used to calculate properties such as pressure, temperature, specific volume, enthalpy, entropy, quality, internal energy and specific heat at constant pressure and volume. CATT3 can also perform various processes such as isobaric, isothermal, isentropic, isochoric and polytropic.


Why is CATT3 useful?




CATT3 is useful because it can help users to solve thermodynamic problems faster and more accurately than using traditional printed tables. CATT3 can handle a wider range of values and substances than printed tables. CATT3 can also display results in different units and formats according to user preferences. CATT3 can also generate graphical representations of thermodynamic data that are easier to understand and analyze.


What are the main features of CATT3?


The main features of CATT3 are:



  • It has a graphical user interface (GUI) that allows users to select the substance, the units and the input parameters.



  • It can calculate output properties in a table or a chart based on input parameters.



  • It can plot diagrams such as T-s, P-v, P-h and h-s for different substances.



  • It can perform processes such as isobaric, isothermal, isentropic, isochoric and polytropic.



  • It can handle substances such as water, air, gases, refrigerants and psychrometric properties.



How to download and install CATT3?

  • If the file is in .rar format, extract it using a software such as WinRAR or 7-Zip.



  • Run the CATT3.exe file or the setup.exe file in the extracted folder.



  • Follow the instructions on the screen to complete the installation process.



How to launch CATT from desktop or start menu?




To launch CATT from desktop or start menu users need follow these steps:



  • Find CATT icon on desktop or start menu.



  • Double-click on icon open CATT.



How use CATT?




How select substance units?




To select substance units users need follow these steps:



  • Select substance from drop-down menu on top left corner of GUI.



  • Select units from drop-down menu on top right corner of GUI.




How enter input parameters calculate output properties?




To enter input parameters calculate output properties users need follow these steps:



  • Select input parameters from radio buttons on left side of GUI.



  • Enter values of input parameters in text boxes on left side of GUI.



  • Click Calculate button see output properties in table or chart on right side of GUI.




How view results in table or chart?




To view results in table or chart users need follow these steps:



  • Select Table or Chart from radio buttons on top right side of GUI.



  • If Table selected view output properties in tabular form with columns for property name symbol value.



  • If Chart selected view output properties in graphical form with x-axis for property name y-axis for value.




How plot diagrams for different substances?




To plot diagrams for different substances users need follow these steps:



  • Select Plot from radio buttons on bottom right corner of GUI.



  • Select diagram type from drop-down menu on top right corner of plot window.



  • Select substance from drop-down menu on bottom left corner of plot window.



  • Select units from drop-down menu on bottom right corner of plot window.



  • View diagram with x-axis y-axis for selected properties curves for selected substance.




Example using CATT




How calculate plot some properties water at different pressures temperatures?




To calculate plot some properties water at different pressures temperatures we need follow these steps:



  • Select Water from substance menu.



  • Select SI from units menu.



  • Select Pressure Temperature from input parameters radio buttons.



  • Enter 100 kPa for pressure 100 C for temperature in text boxes.



  • Click Calculate button see output properties in table. We can see that water at this state has specific volume of 1.043 m^/kg , enthalpy of 2676 kJ/kg , entropy of 7.355 kJ/kg-K , quality of 1 (saturated vapor).



  • Click Plot button see diagrams for water. We can see that water at this state lies on saturation curve on all four diagrams (T-s , P-v , P-h , h-s ).



  • Change pressure value to 10 MPa click Calculate again. We can see that water at this state has specific volume of 0.001127 m^/kg , enthalpy of 762.81 kJ/kg , entropy of 2.138 kJ/kg-K , quality of 0 (saturated liquid).



  • Click Plot again see how water at this state lies below saturation curve on all four diagrams.

FAQs




Q: What are thermodynamic tables?


A: Thermodynamic tables are tables that contain values of thermodynamic properties for different substances at various states.


Q: What are thermodynamic properties?


A: Thermodynamic properties are physical quantities that describe the state and behavior of a substance under different conditions.


Q: What are thermodynamic processes?


A: Thermodynamic processes are changes in state or condition of a substance due to energy transfer or work done.
