MCQ
The efficiency of a Carnot's engine working between steam point and ice point is:
- ✓$26.81\%$
- B$29\%$
- C$30\%$
- D$10\%$
✓
Answer
Correct option: A.
$26.81\%$
$T_1 = (100 + 273) = 373K$
$T_2 = (0 + 273) = 273K$
Efficiency $(\eta)=1-\frac{\text{T}_2}{\text{T}_1}$
$=1-\frac{273}{373}=\frac{100}{373}$
$\%\eta=\frac{100}{373}\times100$
$=26.81\%$
$T_2 = (0 + 273) = 273K$
Efficiency $(\eta)=1-\frac{\text{T}_2}{\text{T}_1}$
$=1-\frac{273}{373}=\frac{100}{373}$
$\%\eta=\frac{100}{373}\times100$
$=26.81\%$
