Q25) A Carnot cycle heat engine operates between 337 K and 590 K. Its efficiency is ____%.
4. A refrigeration unit operates in an inverted Carnot cycle. It receives from the surroundings (at 27°C) 10,000 kcal per hour. If the temperature inside the unit must be kept at -50°C, what is the power of the unit's engine (recall that power is P = W/t)? A Carnot engine is an idealized, reversible engine. In real life, it is found that you need to use an engine capable of producing 5.50 kW to run this unit. Express the efficiency...
