Target entity: Rankine cycle
Context triple: [K15 pressurized water reactor, steamCycle, Rankine cycle]
  • A. Brayton cycle
    The Brayton cycle is a thermodynamic cycle commonly used in gas turbine engines, where air is compressed, mixed with fuel and combusted, and then expanded through a turbine to produce work.
  • B. Carnot cycle
    The Carnot cycle is an idealized thermodynamic cycle that defines the maximum possible efficiency any heat engine can achieve when operating between two temperature reservoirs.
  • C. Carnot
    Carnot is a French surname most famously associated with mathematician and physicist Sadi Carnot, a founder of thermodynamics, and several prominent political and military figures in France.
  • D. Carnot efficiency
    Carnot efficiency is the theoretical maximum efficiency that any heat engine can achieve when operating between two temperatures, serving as a fundamental limit in thermodynamics.
  • E. Linde process
    The Linde process is an industrial gas liquefaction method that enabled large-scale production of liquid air and its components, such as oxygen and nitrogen, revolutionizing refrigeration and gas separation technologies.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
