30. All terms are assumed to be positive. The total work done by the two-stage system is W 1 + W 2 .Th e heat-intake (from, say, consuming fuel) of the system is Q 1 so we have (by Eq. 21-9 and Eq. 21-6) ε = W 1 + W 2 Q 1 = ( Q 1 Q 2 )+( Q 2 Q 3 ) Q 1 =1 Q 3 Q 1 .

Unformatted text preview: Q 1 T 1 = Q 2 T 2 = Q 3 T 3 where we assume Q 2 is absorbed by the second stage at temperature T 2 . This implies the eciency can be written = 1 T 3 T 1 = T 1 T 3 T 1 ....
