Introduction




What is thermodynamics?




Thermodynamics is the branch of physics that deals with the relationships between heat, work, energy, and matter. It studies how these quantities can be transferred and transformed from one system to another, and how they affect the state and behavior of the system. Thermodynamics has many applications in engineering, chemistry, biology, geology, astronomy, and other fields.


What are thermodynamic tables?




Thermodynamic tables are tables that list the values of various thermodynamic properties for different substances at different conditions. Thermodynamic properties are characteristics of a system that describe its state and behavior, such as pressure, temperature, volume, density, enthalpy, entropy, etc. Thermodynamic tables can help us find these properties without having to perform complicated calculations or measurements.


Why are thermodynamic tables useful?




Thermodynamic tables are useful because they can help us solve many problems and applications involving thermodynamics. For example, we can use thermodynamic tables to find the amount of heat or work required or produced by a process, the efficiency or performance of a device or system, the phase or state changes of a substance, etc. Thermodynamic tables can also help us understand the physical phenomena and principles behind thermodynamics.


Thermodynamics Cengel 7th Edition




Who is Yunus Cengel?




Yunus Cengel is a professor emeritus of mechanical engineering at the University of Nevada, Reno. He is also an author and co-author of several textbooks on thermodynamics, fluid mechanics, heat transfer, and related topics. He has received many awards and honors for his teaching and research excellence.


What are the features of his thermodynamics book?




The book "Thermodynamics: An Engineering Approach" by Yunus Cengel and Michael Boles is one of the most popular and widely used textbooks on thermodynamics. It covers both classical and modern topics in thermodynamics with an emphasis on engineering applications. It also provides many examples, exercises, figures, tables, and charts to illustrate and reinforce the concepts and methods. Some of the features of his book are:


  • It uses a simple and intuitive approach to explain thermodynamics.



  • It provides a balanced coverage of both macroscopic and microscopic aspects of thermodynamics.



  • It integrates real-world engineering examples and problems throughout the book.



  • It includes a rich collection of thermodynamic tables and charts in the appendices.



  • It offers online resources and supplements for students and instructors.



How to access the tables in his book?




The tables in his book are available in both print and digital formats. You can access the print version of the tables in the appendices of the book. You can also access the digital version of the tables online or download them as PDF files from the book's website. The website also provides interactive tables that allow you to enter or select the values of the properties and get the results instantly.


Table PDF 12: Properties of Superheated Water Vapor




What is superheated water vapor?




Superheated water vapor is water vapor that is heated above its saturation temperature at a given pressure. Saturation temperature is the temperature at which water vapor and liquid water coexist in equilibrium. When water vapor is heated above its saturation temperature, it becomes superheated and behaves like an ideal gas. Superheated water vapor is commonly used as a working fluid in power plants, turbines, refrigerators, and other devices.


How to use table PDF 12?




Table PDF 12 lists the values of various thermodynamic properties of superheated water vapor at different pressures and temperatures. The table has four columns: pressure, temperature, specific volume, and specific enthalpy. The table is divided into several sub-tables for different pressure ranges. To use table PDF 12, you need to follow these steps:


  • Find the sub-table that corresponds to the pressure of your system.



  • Locate the row that matches the temperature of your system.



  • Read the values of specific volume and specific enthalpy from the table.



  • If the temperature of your system is not listed in the table, you can use interpolation to find the values of specific volume and specific enthalpy.



What are some examples of using table PDF 12?




Here are some examples of using table PDF 12 to solve thermodynamic problems:


Example 1: Find the specific volume and specific enthalpy of superheated water vapor at 1 MPa and 400C.


Solution: From table PDF 12, we find that the sub-table for 1 MPa covers the temperature range from 300C to 600C. We locate the row for 400C and read the values of specific volume and specific enthalpy from the table. The results are:


  • Specific volume = 0.1274 m/kg



  • Specific enthalpy = 3238.9 kJ/kg



Example 2: Find the specific volume and specific enthalpy of superheated water vapor at 0.5 MPa and 350C.


Solution: From table PDF 12, we find that the sub-table for 0.5 MPa covers the temperature range from 250C to 500C. However, there is no row for 350C in the table. Therefore, we need to use interpolation to find the values of specific volume and specific enthalpy. We use the following formula for interpolation:


x = x1 + (x2 - x1) * (T - T1) / (T2 - T1)


where x is the property to be interpolated, x1 and x2 are the values of the property at two adjacent temperatures T1 and T2, and T is the temperature of interest. We choose T1 = 300C and T2 = 400C as the two adjacent temperatures in the table. The values of specific volume and specific enthalpy at these temperatures are:


  • v1 = 0.2558 m/kg



  • v2 = 0.1866 m/kg



  • h1 = 3059.6 kJ/kg



  • v

FAQs




Here are some frequently asked questions about thermodynamics and thermodynamic tables:


Q: What is the difference between saturated and superheated water vapor?


A: Saturated water vapor is water vapor that is in equilibrium with liquid water at a given pressure and temperature. Superheated water vapor is water vapor that is heated above its saturation temperature at a given pressure.
