Can the lowest pressure corresponding to a certain temperature be found in a steam table?
Thread Content
In Example 3-7 of the third edition of Chemical Engineering Thermodynamics by Chen Zhongxiu, it is stated that according to the steam table, the lowest pressure at 473.15 K is 1.961×103 Pa. How is this value determined? This is clearly not the saturated vapor pressure
The saturation pressure should be the highest pressure at a certain temperature. The reason for the minimum pressure is unclear; why can’t it be reduced any further?
Could the original problem post be shared so that it can be analyzed in context? I’ll also share the steam table from the original textbook, okay?
Thank you all; the issue has been resolved. What was needed was to find the lowest pressure of superheated steam at this temperature, so that it could be treated as an ideal gas – as the pressure is lower, the behavior is more similar to that of an ideal gas.
How can I find the lowest pressure of water vapor at this temperature? Thank you for the answer
