The absolute zero pressure can be attained at a temperature of
A. 0°C
B. -273°C
C. 273 K
D. None of these
Otto cycle is generally more efficient than the Diesel cycle.
In the Otto cycle, heat is added at constant volume, leading to a higher peak temperature and pressure. In the Diesel cycle, heat is added at constant pressure, which results in a lower peak temperature for the same peak pressure.
The Dual cycle, which combines aspects of both Otto and Diesel cycles, can have efficiency that falls between the two. Its efficiency depends on the specific proportions of constant volume and constant pressure heat addition.
Therefore, the correct answer is:A
Option a is correct
Answer is A
Efficiency: Otto cycle>Dual cycle>Diesel cycle
Ans b and c both r correct
Correct answer is option A ... Please check it once guys ....
Correct Answer- A
Hello...I think,answer options A,otto cycle is more efficient than Diesel cycle
