Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

8.35 Consider a Carnot-cycle heat engine with water as the working fluid. The heat transfer to the water occurs at 300°C, during which process the water changes from saturated liquid to saturated vapor. The heat is rejected from the water at 40°C. Show the cycle on a T-s diagram and find the quality of the water at the beginning and end of the heat re- jection process. Determine the net work output per kilogram water and the cycle thermal efficiency.
1.) A Carnot engine is coupled to a Carnot refrigerator so that all the work produced by the engine is used by the refrigerator in extraction of heat from a heat reservoir at 270K at the rate of 4 kJ/s. The source of energy for the Carnot engine is a heat reservoir at 500K. If both devise discard heat to the surrounding at 300K, a. How much heat does the engine absorb from the 500K reservoir? b.
