## Steam Tables

1. The problem statement, all variables and given/known data
Steam at 8 MPa and 500 C flows through a valve, where it exits at 100 kPa. What is the exit temperature?

2. Relevant equations
????

3. The attempt at a solution
Looked up both pressures on the steam tables. Not sure how to correlate them as I have never used them before.

 Recognitions: Gold Member First, find out the properties of the steam at the inlet conditions. For example steam at 8 MPa and 500 C is superheated steam. This is because the saturation temperature for steam at 8 MPa is 295.06 C. Since 500 C is greater than 295.06 C the steam is superheated. Now it flows through the valve and it's pressure drops and so does it's temperature. So what you should do is look up the properties at this pressure. Think you can figure out the exit temperature now? Thanks Matt
