Hello, 1. The problem statement, all variables and given/known data Engine A receives four times more input heat, produces six times more work, and rejects three times more heat than engine B. Find the efficiency of (a) engine A and (b) engine B. 2. Relevant equations e = |W|/|QH| e = 1 - |Qc|/|QH| 3. The attempt at a solution I can't really see how i'm supposed to find any numerical answer to this question. It seems overly simple just to state the efficiency of A in terms of B and vice versa. What relationship am I not seeing that will help me solve this problem? Thanks for any help you can give.
