A Carnot engine has an efficiency of 0.445, and the temperature of its cold reservoir is 434 K. (a) Determine the temperature of its hot reservoir. (b) If 5610 J of heat is rejected to the cold reservoir, what amount of heat is put into the engine?
Homework Answers
(a) Carnot effieciency,
η = (Thot-Tcold)/Thot
0.445=1-434/Thot
434/Thot = 0.555
Thot=781.98 K
Amount of heat is put in the engine,
Carnot effieciency,
η =(Qsupplied-Qrejected) /Qsupplied
0.445 =1-Qrejected/Qsupplied
Qrejected/Qsupplied=0.555
Qsupplied =5610/0.555 = 10108.1081 J
