Consider a steam power plant that operates on a reheat Rankine cycle and has a net power output of 80 MW. Steam enters the high-pressure turbine at 10 MPa and 500°C and the low-pressure turbine at 1.4 MPa and 500°C. Steam leaves the condenser as a saturated liquid at a pressure of 10 kPa. Assume both turbine and compressor are isentropic. Determine the quality (or temperature, if superheated) of the steam at the turbine exit. The quality of the steam at the turbine exit is 927

### Steam Power Plant Analysis **Scenario:** Consider a steam power plant that operates on a reheat Rankine cycle and has a net power output of 80 MW. Steam enters the high-pressure turbine at 10 MPa and 500°C and the low-pressure turbine at 1.4 MPa and 500°C. Steam leaves the condenser as a saturated liquid at a pressure of 10 kPa. Assume both the turbine and compressor are isentropic. **Task:** Determine the quality (or temperature, if superheated) of the steam at the turbine exit. **Solution:** The quality of the steam at the turbine exit is **0.927**. **Explanation:** - The plant uses a reheat Rankine cycle, increasing efficiency by reheating the steam between turbine stages. - Isentropic processes imply that there is no entropy change during the expansions and compressions. This represents a typical scenario for examining efficiency and energy conversion in thermal power systems.
