Please circle one correct answer to each problem. There is no partial credit given for these FE type problems. A Carnot cycle consists of Two constant temperature ami two constant volume processes Two isothermal and two constant pressure processes Two isothermal and two adiabatic processes Two adiabatic and two isobaric processes Which of the following statements is true for both turbine and nozzle? Gas flow in both turbine and nozzle are being accelerated Enthalpy at the exit is higher than enthalpy at the inlet for both turbine and nozzle Both turbine and nozzle generate work output Actual adiabatic turbine and nozzle have higher entropy at the exit than at the inlet What is the Carnot efficiency of a power cycle that receives 100 kJ of heat from a hot reservoir at 600 degree C and rejects 47 kJ of heat to a cold reservoir at 110 degree C? 53% 82% 56% 67% What is the Carnot efficiency of a power cycle that receives 100kJ of heat from a hot reservoir at 600 degree C and rejects 47KJ of heat to a cold reservoir at 110 degree C? 53% 82% 56% 67% The change in entropy between states 1 and 2 of an internally reversible process is 2.5 kJ/K. What is the change in entropy between the same states 1 and 2 if the process is irreversible. 2.5 kJ/K Lower than 2.5 kJ/K Higher than 2.5 KJ/K 2.5 kJK ? entropy production For an internally reversible process of a closed system, the area under a temperature - entropy curve represents Work Entropy production Kelvin scale Heal transferExplanation / Answer
