Question 1

Determine whether water at each of the following states is a compressed liquid, a superheated vapor, or a mixture of saturated liquid and vapor.

Question 2

All cases

a.2 lbf/in.2, 50 F: compressed liquid P > Psat(T) = 0.178

b. 270 F, 30 lbf/in.2: sup. vapor P < Psat(T) = 41.85 lbf/in2

c. 160 F, 10 ft3/lbm vg = 77.22, vf = 0.0164 ft3 /lbm, so liquid + vapor mixture

States shown are placed relative to the two-phase region, not to each other.
