Problem 1E
A diesel engine performs 2200 J of mechanical work and discards 4300 J of heat each cycle. (a) How much heat must be supplied to the engine in each cycle? (b) What is the thermal efficiency of the engine?
Step-by-Step Solution:
Solution 2E Step 1: Mechanical work output is QH = 9000 J W =16400 J Hence we have Total mechanical work is s\ W=QH W 1 W = 9000 J 6400 J = 2600 J Mechanical output is 2600 J
