A tank contains a liquid-vapor mixture of water at 100 kPa with a specific volume of 0.5 m3/kg. If vf = 0.001043 m3/kg and vg = 1.694 m3/kg, what is the quality?

  1. 0.2952
  2. 0.7053
  3. 0.2947
  4. 0.2950

Answer

C. 0.2947

Solution

x = (v - vf)/(vg - vf) = (0.5 - 0.001043)/(1.694 - 0.001043) = 0.2947.
