Problem 8.1 - A 10 MPa Steam Power Plant with an Open Feedwater Heater
Consider the steam power plant with an open feedwater heater operating under the conditions shown in the following diagram:
Carefully draw the complete cycle above on
the pressure-enthalpy [P-h] diagram provided below, indicating
clearly all 9 stations on the diagram.
Using the conditions shown on the diagram above and values obtained from the Steam Tables:
Note: Justify all values used and derive all equations used starting from the basic energy equation for a flow system, and basic definition of thermal efficiency of a heat engine.
