Question

What is the efficiency of the system, if the actual work output from the process is 15 J and work output for a reversible process is 20 J?

(a) 25%

(b) 50%

(c) 75%

(d) 100%

I got this question in my homework.

I need to ask this question from Efficiency topic in section Energy Balances that Include the Effects of Chemical Reaction, Ideal Processes, Efficiency and the Mechanical Energy Balance and Heats of Solution and Mixing of Basic Chemical Engineering

Answer 1

Right option is (c) 75%

To explain: Efficiency = 15/20*100 = 75%.
