Consider two reversible power cycles, R1 and R2, are operating between the same two hot and cold thermal reservoirs at temperatures of 1000 K and 500 K respectively. If work output from power cycle R1 is three times more than the work output of power cycle R2, which of the following statements are correct? Select more than one answer if applicable. Da. Thermal efficiency of power cycle R1 is three more than the thermal efficiency of power cycle R2. b. Energy rejected by heat transfer from power cycle R1 is three times more than the energy rejected by heat transfer from power cycle R2. Oc. The actual thermal efficiency of power cycle R1 is equal to the maximum thermal efficiency of power cycle R2. Od. Energy received by heat transfer by the two power cycles are the same. e. The work output from the combined power cycle (combining power cycles R1 and R2) will be 50% more that the work output of power cycle R1.
