At 250 psi, water has vf = 0.01865 ft3/lbm and vg = 1.845 ft3/lbm. A saturated mixture of water at 250 psi has a quality of 0.71.

(a) Determine the specific volume of the water.
(b) If the water occupies a volume of 10 ft3, determine the mass of the water.

Given: vf = 0.01865 ft3/lbm; vg = 1.845 ft3/lbm; x = 0.71

What will be an ideal response?What will be an ideal response?


(a) v = x(vg-vf) + vf = 1.32 ft3/lbm

(b) V = 10 ft3: m = V/v = 7.60 lbm
