Problem 8.3 - A Reheat Steam Power Plant with a Closed Feedwater Heater

Consider the reheat steam power plant shown below which has been augmented with a Closed Feedwater Heater in an attempt to increase the thermal efficiency.

Justify all values used and derive all equations used starting from the basic steady flow energy equation, the basic equation of enthalpy change (Δh) for an incompressible liquid. and the basic definition of thermal efficiency (ηth)

Consider the two adiabatic turbines only in the reheat steam power plant shown above.

Justify all values used and derive all equations used starting from the basic steady flow energy equation and the basic definition of turbine adiabatic efficiency ηT.
