23. The Second Law of Thermodynamics / Heat Engines & PV Diagrams / Problem 6
A mechanical engineering student built a coal-fired power plant prototype. First, the coal is burned in a boiler, producing 2750 W of heat. The heat from the burning coal is used to boil water, and the produced high-pressure steam causes the blades of a turbine to spin. As a result, 220 W of electrical power is generated. Determine the prototype power plant's efficiency.
