second law of thermodynamics

A refrigerator is coupled with a Carnot heat engine as a system. The heat engine absorbs heat

from a hot reservoir at 220°C and rejects waste heat to cold reservoir at 25°C. The absorbed

heat is converted to work by the heat engine and supply to the refrigerator to produced ice.

The ice is formed at cold reservoir of refrigerator at 0°C and the refrigerator rejected 63 kW of

heat to the hot reservoir at 25°C. By assuming the system operates based on the Carnot cycle,

determine the following:

a. The coefficient of performance (COP) of the refrigerator.

b. The power output of the heat engine.

c. The efficiency of the heat engine.

Second Law of Thermodynamics Learning Goal: To understand the implications of the second law of thermodynamics. The second law of thermodynamics explains the direction in which the thermodynamic processes tend to go. That is, it limits the types of final states of the system that naturally evolve from a given initial state. The second law has many practical applications. For example it explains the limits of efficiency for heat engines and refrigerators. To develop a better understanding of this law,...
