Final answer:
The reheat Rankine cycle is commonly used in steam power plants. By analyzing the given values, we can determine the quality of the steam at the turbine exit, the thermal efficiency of the cycle, and the mass flow rate of the steam.
Step-by-step explanation:
The reheat Rankine cycle is a thermodynamic cycle commonly used in steam power plants. In this cycle, steam enters the high-pressure turbine at a temperature of 500°C and a pressure of 10 MPa. The isentropic efficiency of the turbine is given as 80%. The steam then enters the low-pressure turbine at a pressure of 1 MPa and the same temperature of 500°C.
The cycle is completed by condensing the steam in the condenser, where it becomes a saturated liquid at a pressure of 10 kPa. Using these values, we can now determine the quality (or temperature if superheated) of the steam at the turbine exit, the thermal efficiency of the cycle, and the mass flow rate of the steam.
