Properties of Water-Steam Mixture
The following properties of
water-steam mixture can be found using Steamulator:
T, P, X, V, Vf, Vfg, Vg, U, Uf,
Ufg, Ug, H, Hf, Hfg, Hg,
S, Sf, Sfg, Sg
if any one pair of the following properties is given:
(T, X), (T, V), (T, U), (T, H), (T, S), (P, X), (P, V), (P, U), (P,
H), (P, S), (X, V), (X, U), (X, H), (X, S), (V, U), (V, H), (V, S),
