Problem 21E
You design an engine that takes in 1.50 × 104 J of heat at 650 K in each cycle and rejects heat at a temperature of 350 K. The engine completes 240 cycles in 1 minute. What is the theoretical maximum power output of your engine, in horsepower Section 20.7 Entropy
ANSWER:Solution 21E
Step 1:
Heat absorbed QH = 1.5x104J
Temperature at hot reservoir TH = 650K
Temperature at cold reservoir TC = 350K
No of cycles completed = 240
Time taken t = 1 min or 60s
