Real Rankine Cycle with Superheat Given: A steam power cycle with known properties and operating parameters as shown below. Find: The net power developed (hp) The thermal efficiency The heat rate The back work ratio The mass flow rate of the cooling water
Real World Example Strategy: Build a property table, then do the thermodynamics. Knowing the isentropic efficiency allows for the calculation of the actual exit enthalpy
Now that the properties are all known, the thermodynamics is EESy!
