Problem: Exergy Analysis of a Rankine Cycle Power PlantA Rankine cycle power plant runs with steam as the working fluid. The steam is produced in a boiler at high pressure and temperature, expanded in a turbine, and condensed in a condenser before being brought back to the boiler. Let's take some of the scenarios:The Rankine cycle is ideal and operates in a steady state.The working fluid behaves as an ideal gas.The pump and turbine are adiabatic and reversible.There are no pressure drops in the condenser and boiler.Let's take standardized data:Boiler pressure (high pressure): Turbine inlet pressure: Turbine inlet temperature: Condenser pressure: Pump inlet pressure: The mass flow rate of steam: Specific heat capacity of steam: Specific heat capacity of water: Sub-Question 1: Determine the specific enthalpies at each stage of the Rankine cycle.Solution:a) State 1 (boiler exit):Using the steam tables or property relations for water and steam, calculate the enthalpy at state 1 ( ) given the pressure and considering the fluid is saturated.b) State 2 (turbine inlet):Using the steam tables or property relations for water and steam, find the enthalpy at state 2 ( ) given the pressure and temperature .c) State 3 (condenser exit):Since the condenser pressure is lower than the saturation pressure at state 3, the steam will be in the subcooled region. Calculate the enthalpy at state 3 ( ) using the specific heat capacity of water ( ) and the temperature at state 3.d) State 4 (pump exit):Since the pump is adiabatic and reversible, the specific enthalpy at state 4 ( ) will be equivalent to state 3.
