Sketch an ideal vapour-compression refrigeration cycle on p-v, t-s and p-h diagrams, and describe the processes that make up this cycle. (4 marks) list the properties of an ideal refrigerant. (3 marks) an ideal vapour-compression refrigeration cycle uses refrigerant-134a as a working fluid in an air- conditioning system. the refrigerant enters the compressor as a saturated vapour at 5°c and leaves the condenser as a saturated liquid at 55°c. the mass flow rate of the refrigerant is 0.7 kgs-1. heat transfer to the refrigerant in the evaporator is from a reservoir at 15°c, and the refrigerant in the condenser is cooled by heat transfer to the environment, which is at a temperature of 45° • the heat-transfer rate in the condenser the heat-transfer rate in the evaporator • the coefficient of performance of the cycle

Before it was launched, a helium-filled balloon had a pressure of 201 kpa at a temperature of 27°c. at an altitude of 15,000 m, the pressure had decreased to 2.5 kpa and the temperature had dropped to -14 °c. the volume of the balloon increased to 59.3 m3. what is the original volume of the balloon? 13 m3 0.85 m3 0.077 m3 1.17 m3
