1. The problem statement, all variables and given/known data I have a table for 5 sets of data. Each set includes data from one ore more of the following properties - temperature, pressure, energy, and steam quality. I have to look at steam tables for water to find the missing values. For the data set in question I'm given T = 75 C, and P = 500 KPa. I need to find the energy and steam quality, and from steam quality I get number of phases present. 2. Relevant equations for finding x or energy if calculation is required - u = x*(u liquid) + ((1-x)*(u gas)) just rearrange the above to find x if needed 3. The attempt at a solution One of the data sets gives me a temperature and pressure of 75 C and 500 KPa, nothing else. I looked at water's saturated steam tables for this temperature and pressure. I found that P>Saturated Pressure and T<Saturated Temperature (at these given values), so I'm assuming that I'm actually looking at a compressed liquid. I then looked at the steam tables for compressed liquid, but I can't find a data set for 75 C and 500 KPa. The temperature range includes 75 C, but all the pressures are in the multiple MPa's. Can someone help me clarify how to properly approach these tables? I'm a bit confused here. Any and all help is appreciated, thank you.
