Consider a 100-MW Rankine-cycle steam power plant. The peak cycle temperature is 1000 F. The condenser pressure is 1 psia. Plot the first-law thermal efficiency and mass flow rate (Mlb_m/hr) as functions of the boiler pressure (from 1 to 1000 psia using a semilogarithmic scale). Perform all calculations without the aid of EES or a spreadsheet on a computer. The NIST online database, however, may be useful to obtain any required thermo dynamic properties.
