(a) Explanation Write the expression for the quality of the mixture. x 100 ° F = v − v f 1 v g 1 − v f 1 (I) Here, the quality of ammonia at 100 ° F is x 100 ° F , specific volume of saturated liquid ammonia at 100 ° F is v f 1 and the volume of the saturated vapour ammonia at 100 ° F is v g 1 . Conclusion: Refer to the Table A − 13 E “properties of the saturated ammonia (Liquid-Vapour): Temperature Table” at 100 °F obtaining the value of v f 1 as 0.02747 ft 3 / lb and v g 1 as 1.4168 ft 3 / lb . Substitute 1 ft 3 / lb for v , 0.02747 ft 3 / lb for v f 1 and 1 (b) To determine The quality of the mixture at 0 ° F . The location of the mixture on the T − v diagram.
