Consider a 20-MW cogeneration power plant in a campus complex. An energy balance analysis indicates the following energy fluxes for the power plant:

It is estimated that all the condenser losses but only 12 percent of the stack losses can be recovered. Determine both the overall thermodynamic efficiency and the PURPA efficiency of the power plant.
