(I) A heat engine’s high temperature TH could be ambient
Chapter 15, Problem 22P(choose chapter or problem)
(I) A heat engine’s high temperature \(T_{H}\) could be ambient temperature, because liquid nitrogen at 77 K could be \(T_{L}\) and is cheap. What would be the efficiency of a Carnot engine that made use of heat transferred from air at room temperature (293 K) to the liquid nitrogen “fuel”(Fig.15–25)?
