Which one of the following cycles working within the same temperature ...
The Rankine Cycle has the highest work ratio among the given cycles.
Explanation:
The work ratio of a cycle is defined as the ratio of the net work output to the total heat input.
To determine which cycle has the highest work ratio, we need to compare the work ratios of each cycle.
Carnot Cycle:
- The Carnot cycle is an idealized thermodynamic cycle that consists of four reversible processes: isentropic compression, constant temperature heat addition, isentropic expansion, and constant temperature heat rejection.
- The work ratio of the Carnot cycle is given by the equation:
Work ratio = (T1 - T2) / T1, where T1 and T2 are the maximum and minimum temperatures in the cycle.
- Since the Carnot cycle operates within the same temperature limits as the other cycles, its work ratio will be the same as the other cycles.
Joule Cycle:
- The Joule cycle is a constant volume cycle that consists of two reversible processes: isochoric heat addition and isochoric heat rejection.
- The work ratio of the Joule cycle is given by the equation:
Work ratio = (T1 - T2) / T1
- Since the work ratio equation for the Joule cycle is the same as the Carnot cycle, its work ratio will be the same as the other cycles.
Otto Cycle:
- The Otto cycle is an idealized cycle that represents the operation of spark-ignition internal combustion engines.
- The work ratio of the Otto cycle is given by the equation:
Work ratio = (T1 - T2) / T1
- Since the work ratio equation for the Otto cycle is the same as the Carnot and Joule cycles, its work ratio will be the same as the other cycles.
Rankine Cycle:
- The Rankine cycle is an idealized cycle that represents the operation of steam power plants.
- The work ratio of the Rankine cycle is given by the equation:
Work ratio = (T1 - T2) / T1
- Since the work ratio equation for the Rankine cycle is the same as the Carnot, Joule, and Otto cycles, its work ratio will be the same as the other cycles.
Conclusion:
Since all the given cycles have the same work ratio equation and operate within the same temperature limits, they will have the same work ratio. Therefore, the answer is option D - Rankine cycle.

Since all the given cycles have the same work ratio equation and operate within the same temperature limits, they will have the same work ratio. Therefore, the answer is option D - Rankine cycle.
