Chapter 2, Problem 2.1P

Are the pressure in the tables absolute or gauge pressure?

Expert Solution & Answer
Check Mark
To determine

Type of pressures in the tables.

Explanation of Solution

In all thermodynamic tables, the pressure is taken as absolute. Absolute pressure is the pressure above atmospheric pressure.

Water has the same chemical composition in all three phases be it water, ice or steam. So, water is a pure substance. The behavior of pure substances depends on absolute pressure.

In the thermodynamic steam table, two steam table is given for water that is saturation steam table and superheated steam tables. In both, the table absolute pressure is given for the ease of calculation.
