Answer : Option D
Explanation :
An hmh flame speed is obtained in diesel engine when air fuel ratio is About 10% of rich mixture. The flame speed is the measured rate of expansion of the flame front in a combustion reaction. Whereas flame velocity is generally used for a fuel. Combustion engineers differentiate between the laminar flame speed and turbulent flame speed. Flame speed is typically measured in m/s, cm/s, etc.
