The temperature of a Carnot refrigerator’s cold reservoir is . The hot reservoir has a temperature of . What is the coefficient of performance of the Carnot refrigerator?
A Carnot engine performs 100 J of work while rejecting 200 J of heat each cycle. After the temperature of the hot reservoir only is adjusted, it is found that the engine now does 130 J of work while discarding the same quantity of heat.
What is the initial efficiency of the engine?
What is the final efficiency of the engine?
What is the fractional change in the temperature of the hot reservoir?
A Carnot engine working between two heat baths of temperatures 600 K and 273 K completes each cycle in 5.00 s. In each cycle, the engine absorbs 10.0 kJ of heat. Find the output power of the engine.
