1. 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

2. Real World Example

3. 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

4. Now that the properties are all known, the thermodynamics is EESy!
