Reading properties from a steam table

physea · Feb 10, 2018

Hello!
I see this Steam table:

Saturated water and steam table listing pressure p in bar, temperature ts in °C, specific volumes vf and vg in m³/kg, internal energy uf, ufg and ug in kJ/kg, enthalpy hf, hfg and hg in kJ/kg, and entropy sf, sfg and sg in kJ/(kg K).

Handwritten-style unit conversion working of hf/kJ per kg equals pvf in bar times m3/kg, giving 0.006112 times 0.0010002 times 10^2 = 0.0006112.

It shows Vg but not Vf. It mentions some equations at the bottom. Does anyone know how much is Vf for 0.1bar?

you could widen the question: does anyone know what You mean with Vf? ?

if you want the specific volume of the liquid, find another table that shows it...e.g. cengel

I would expect a table such as this to list v_f. However since u = h - pv, then
v by calculation is: v = (h - u)/p.
