The Attempt at a Solution
I understand that for figure A, Qh=T1Δs and Qc=(T1-T2)Δs once you take the negative out of the Δs. For figure B, Qh=(T2-T1)Δs and Qc=-T2Δs once you take the negative out of the Δs. For the efficiency of figure A, I got η=T2/T1 after plugging into 1-Qc/Qh. For figure B, I got η=(2T2-T1)/(T2-T1). I have a feeling that what I have for figure A is right but that B is no where close. Any help would be awesome
