Question

During each cycle a reversible engine absorbs 2400Jof heat from a high-temperature reservoir and performs 2100Jof work. During each cycle a reversible engine absorbs 2400Jof heat from a high-temperature reservoir and performs 2100Jof work. During each cycle a reversible engine absorbs 2400Jof heat from a high-temperature reservoir and performs 2100Jof work. Part A What is the efficiency of this engine? e= Submit Part A What is the efficiency of this engine? e= Submit e= e= Submit Part B How much heat is exhausted to the low-temperature reservoir during each cycle? Qc= J Submit Part B How much heat is exhausted to the low-temperature reservoir during each cycle? Qc= J Submit Qc= J Qc= J Submit Part C Th/Tc= Submit Th/Tc= Th/Tc= Submit e=

Explanation / Answer

a) e = 2100/2400 = 0.875

b) Q = 2400 - 2100 = 300 J

c) e = 1- Tc/Th = 0.875

Th/Tc = 8
