Question A2 a. Saturated liquid water is at 270°C. What is its pressure and specific volume? How much energy would be required to convert 4kg of the water into saturated vapour? [40%] Answer: 6418.4) b. Define the quality of a saturated mixture. (20%) Answer: The quality of a saturated mixture describes the amount of saturated vapour and saturated liquid present. It is a ratio of the mass of vapour to the total mass, and can be used to calculate volume and enthalpy changes. {show on a property diagram} C. 10 kg of refrigerant R-134a at 300 kPa fills a rigid container whose volume is 14 litres. Determine the temperature, quality and enthalpy of the saturated mixture. (40%) Answer: T=0.61°C, x = 0.009321, h = 545.2 kJ
