Need help with this engineering problem. Make sure you circle the answers.

 

For each cycle determine:

(a) the net power developed per unit mass of steam flowing for the Rankine and Carnot cycle, in kJ/kg.

(b) the percent thermal efficiency for the Rankine and Carnot.

### Thermodynamic Cycle Representation and State Data #### Graph Explanation The graph displayed is a Temperature-Entropy (T-s) diagram representing a thermodynamic cycle. The y-axis represents the temperature \(T\) while the x-axis represents the entropy \(s\). Key states in the cycle are marked and connected with lines forming a closed loop, indicating the various processes the substance undergoes. The graph features two notable pressure lines: - **100 bar pressure line**: Starting at state 1 and going to state 4' - **1 bar pressure line**: Starting at state 2 and going to state 3 The states indicated on the graph are: - **State 1**: At high temperature and high entropy. - **State 2**: At lower temperature and entropy compared to state 1. - **State 3**: Slightly lower temperature and entropy than state 2. - **States 3' and 4'**: Intermediate within the cycle showing various transformations. #### Data Table A detailed data table accompanies the graph, summarizing the properties of different states within the cycle: | State | \( p \) (bar) | \( h \) (kJ/kg) | \( x \) | \( v \) (m³/kg) | |-------|---------------|-----------------|---------|-----------------| | 1 | 100 | 2724 | 1 | - | | 2 | 1 | 2024 | 0.7117 | - | | 3' | 1 | 1184 | 0.3396 | - | | 3 | 1 | 417.9 | 0 | 0.001043 | | 4 | 100 | 428.3 | -- | - | | 4' | 100 | 1408 | 0 | - | #### Definitions: - **State**: Indicates different stages in the thermodynamic cycle. - **\( p \) (bar)**: Pressure in bars. - **\( h \) (kJ/kg)**: Specific enthalpy in kilojoules per kilogram. - **\( x \)**: Quality (fraction of vapor in the mixture, dimensionless). - **\( v \) (m³/kg)**:
