Problem Set #5 Steam Plant Efficiency 1. A heat engine has a thermal efficiency of 25% at a steady power output of 900 kW. Calculate the fuel flow rate (the amount of fuel going into the combustion chamber) in kilograms per second [%] if the fuel is wood, with an energy content of 15 1%. 2. Calculate the maximum possible efficiency for an ideal, frictionless, heat engine with: a. Th = 145C, Tc = 23 C b. Th = 250C, Tc = 23 C c. Th = 250C, Tc = 0 C
