```markdown ### Thermodynamics: First Law Questions 86-90 are based on the stated information listed below. A simple vapor power plant operates at steady state conditions. Assume the turbine and pump processes are adiabatic and that kinetic and potential energy effects are negligible. #### State Data | State | u (kJ/kg) | h (kJ/kg) | |-------|-----------|-----------| | 1 | 173.9 | 173.9 | | 2 | 332.6 | 342.8 | | 3 | 3085.6 | 3425.1 | | 4 | 2206.2 | 2336.7 | **Components of the System:** - HP Hex (High Pressure Heat Exchanger) - Pump - Turbine - LP Hex (Low Pressure Heat Exchanger) #### Multiple Choice Questions **86. The turbine work output in kJ/kg is** - a. 3082.3 - b. 1088.4 - c. 168.9 - d. none of the above **87. The pump work input in kJ/kg is** - a. 3082.3 - b. 1088.4 - c. 168.9 - d. none of the above **88. The thermal energy input to the working fluid in kJ/kg is** - a. 3082.3 - b. 1088.4 - c. 168.9 - d. none of the above **89. The net work input to the working fluid in kJ/kg is** - a. 3082.3 - b. 919.5 - c. 168.9 - d. none of the above ``` #### Explanation of Data and Questions The table lists internal energy (u) and enthalpy (h) values for different states of a simple vapor power plant. The questions require calculating work and thermal energy values using these values, assuming adiabatic processes for turbine and pump with negligible kinetic and potential energy effects.
