The specific enthalpy is determined from the thermodynamic quality, x, which has a value between 0 and 1. For x=0, the fluid is all liquid, and for x = 1, the fluid is all vapor.

Specific properties are given by xp

Some discussion and examples: http://www.engineersedge.com/thermodynamics/steam_tables.htm

One should be able to find discussion in a textbook on introduction to thermodynamics.

Density of each phase is a straight lookup in the saturated table.

When you have a mix of liquid and vapor it's just simple algebra to figure density of the mix

i use the one at boilerroomservices dot com, go there and click on click on Boiler Steam Tables,

they give density as specific volume which is 1/density

just look it up for the temperature or pressure you are given.

That's Mother Nature's kind gift to Thermo students - at saturated condition either temp or pressure defines your point on the saturation curve.

i use English units but metric steam tables abound at sites like engineeringtoolbox

boilerroomservices has metric ones too i think, perhaps poke around their site a bit

this is very basic to thermo so master it soon .

BTW two phase flow is not at all simple so you are allowed some initial bewilderment.
