Randall D. Knight β Heat Engines and Refrigerators: Problem 38
The engine that powers a crane burns fuel at a flame temperature of $2000^{\circ}\text{C}$. It is cooled by $20^{\circ}\text{C}$ air. The crane lifts a $2000\text{ kg}$ steel girder $30\text{ m}$ upward. How much heat energy is transferred to the engine by burning fuel if the engine is $40\%$ as efficient as a Carnot engine?
