# Temperature and Pressure Saturation Tables

The type of table that you will use the most in this course is a saturation table.
The first two columns contain the saturation temperature and saturation pressure.
Saturation tables can be arranged in two different ways:
1. Saturation Temperature Table - the table is set up in temperature intervals and is useful when the temperature is known.

2. Saturation Pressure Table - the table is set up in pressure intervals and is useful when the pressure is known.

Normally, there would be columns for additional properties.

In this lesson, we will focus on properties that you already understand: P, T and V.

### Ch 2, Lesson C, Page 2 - Temperature and Pressure Saturation Tables

• We begin with the saturation tables because you will use these more than any other type of table in this course.
• Saturation tables come in 2 flavors: temperature and pressure.
• They are easy to tell apart.  In a saturation temperature table, the left-hand column is the saturation temperature.
• In a saturation pressure table, the left-hand column is the saturation pressure.
• We’ll learn some more about the differences between these two tables in just a couple of pages.
• OK, the saturation tables contain a lot of data that you don’t need to understand just yet.
• We’ll learn all about the other columns in all of the thermodynamic tables in the chapters to come.
• For now, we’ll just work with the saturation temperature, the saturation pressure and the specific volumes of the sat’d liquid and sat’d vapor.
• Now, let’s get down to business and take a look at a real Saturation Temperature Table.
