How to read a Thermodynamic table?

In summary, a thermodynamic table is a chart that displays the thermodynamic properties of a substance at different temperatures and pressures. To read a thermodynamic table, locate the desired substance and corresponding values, and find the corresponding properties in the table. The units used in a thermodynamic table can vary, but commonly include temperature, pressure, and energy. A thermodynamic table can be used to calculate values by interpolating between data points. Not all thermodynamic tables are the same, so it is important to use a reliable and accurate table with consistent units for calculations.

When solving a word problem in Thermodynamics and are given both pressure and tempreature of a fluid or water, how do we know if we should get information about internal energy and entropy from the Pressure Table or the Temperature Table?

Hi Beembo, :welcome:

You could be a bit more specific. Here is a link with the tables you mention (A4 and A5). There is also an A6 etc. What's the problem ?

The tables are equivalent. You might be able to avoid interpolation if you know the temperature or the pressure.
 

1. What is a thermodynamic table?

A thermodynamic table is a chart that presents the thermodynamic properties of a substance at various temperatures and pressures. It includes data such as specific heat, entropy, enthalpy, and other thermodynamic parameters.

2. How do I read a thermodynamic table?

To read a thermodynamic table, locate the substance you are interested in and find the desired temperature and pressure values. Then, the corresponding thermodynamic properties can be found in the columns and rows of the table.

3. What are the units used in a thermodynamic table?

The units used in a thermodynamic table can vary depending on the source. However, common units include Kelvin or Celsius for temperature, bar or kilopascal for pressure, and joules or kilojoules for energy.

4. How can I use a thermodynamic table to calculate values?

A thermodynamic table can be used to calculate values by interpolating between the given data points. This involves finding the closest temperature and pressure values in the table and then using a formula to determine the desired property at the specific conditions.

5. Are all thermodynamic tables the same?

No, thermodynamic tables can vary depending on the source and the specific substance being studied. It is important to use a reliable and accurate table for your calculations, and to ensure that the units are consistent with your calculations.
