The question is incomplete. Here is the complete question.
Two kg of a two phase liquid vapor mixture of carbon dioxide (CO₂) exists at -40°C in a 0.05m³ tank. Determine the quality of the mixture, if the values of specific volume for saturated liquid and saturated vapor CO₂ at -40°C are = 0.896 x 10⁻³m³/kg and 3.824 x 10⁻²m³/kg, respectively.
Answer: x = 1
Explanation: In a phase change of a pure substance, at determined pressure and temperature, the substance exists in two different phases: saturated liquid and saturated vapor.
<u>Quality (x)</u> is the ratio of saturated vapor in the mixture and can be written as:
It has value between 0 and 1: x = 0 for saturated liquid and x = 1 for saturated vapor.
When related with volumes, quality is rearranged as:
Solving for x:
x = 1.3
<u>Quality of mixture of carbon dioxide is x = 1, which means it's for saturated vapor.</u>
