Problem 6E

(a) Calculate the theoretical efficiency for an Otto-cycle engine with ? = 1.40 and r = 9.50. (b) If this engine takes in 10,000 J of heat from burning its fuel, how much heat does it discard to the outside air?

Step-by-Step Solution:

Solution 6E Problem (a) Step 1: To find the theoretical efficiency of the otto-cycle engine Ratio of heat capacity = 1.40 Compression ratio r = 9.50 Step 2: 1 e = 1 r1 1 e = 1 9.5.401 e = 1 0.40 9.5 e = 0.594 or 59.4% The theoretical efficiency of the otto-cycle engine...
