A Carnot engine operates between a high-temperature reservoir at 435 K and a reservoir with water at 280 K. If it absorbs 3700 J of heat each cycle, how much work per cycle does it perform?

Answer :

The required Carnot engine performs 1318.31 J of work per cycle.

What is the Carnot engine?

The Carnot engine is an idealized heat engine that operates between two thermal reservoirs and is the most efficient engine possible for a given set of thermal reservoirs. The efficiency of a Carnot engine is given by the formula:

[tex]Efficiency = 1 - (T_{low} / T_{high})[/tex]

In this problem, the high-temperature reservoir is at 435 K and the low-temperature reservoir is at 280 K. Therefore, the efficiency of the Carnot engine is:

Efficiency = 1 - (280/435) = 0.3563 or 35.63%

The Carnot engine absorbs 3700 J of heat each cycle. Therefore, the work performed per cycle by the engine is:

Work = Efficiency * Heat absorbed
= 0.3563 * 3700 J = 1318.31 J

Therefore, the Carnot engine performs 1318.31 J of work per cycle.
