Using the information below, compute the cycle efficiency:
A) 93.8%.
B) 81.3%.
C) 100.0%.
D) 75.0%.
E) 88.8%.

Question

Quizplus · Accepted Answer

The cycle efficiency of a system is typically calculated using the formula: Efficiency = (Work output / Heat input) * 100. Without specific values for work output and heat input provided in the question, it's impossible to accurately calculate the cycle efficiency. However, given the options, none of the efficiencies provided (93.8%, 81.3%, 100%, 88.8%) are typically achievable in real-world thermodynamic cycles due to inevitable losses (e.g., friction, heat loss). Realistically, no cycle can be 100% efficient due to the second law of thermodynamics, which makes option C incorrect. The highest efficiencies are usually seen in ideal, theoretical cycles, such as the Carnot cycle, but even these do not reach 100%. Among the given options, 75% might be considered a reasonable efficiency for a highly optimized cycle, but without specific context or a formula to apply, this is a speculative choice based on the exclusion of unrealistic options and the principles of thermodynamics.
