Answer:
the efficiency of the Carnot engine is e=0 .5060 (50.96%)
Explanation:
The carnot cycle effifiency e is calculated through
e = W/Q₂
where
W= work
Q₂= heat absorbed
Q₁= heat exhausted
from an energy balance
W= Q₂ - Q₁ ( the proportion of the heat absorbed that was not released was converted to work)
therefore
e=(Q₂-Q₁)/Q₂ = 1 - Q₁/Q₂ = 1 - 51 J/104 J = 0.5060 (50.96%)
