Internal Combustion Engines If V₁ is the jet velocity and V₀ is the vehicle velocity, then propulsive efficiency of a turbojet engine is V₀ / (V₀ + V₁) 2V₀ / (V₀ + V₁) V₁ / (V₀ + V₁) 2V₁ / (V₀ + V₁) V₀ / (V₀ + V₁) 2V₀ / (V₀ + V₁) V₁ / (V₀ + V₁) 2V₁ / (V₀ + V₁) ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines By higher octane number of spark ignition fuel, it is meant that the fuel has Longer ignition delay Higher heating value Higher flash point Lower volatility Longer ignition delay Higher heating value Higher flash point Lower volatility ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines Supercharging is the process of Providing forced cooling air Injecting excess fuel for raising more loads Supplying compressed air to remove combustion products fully Supplying the intake of an engine with air at a density greater than the density of the surrounding atmosphere Providing forced cooling air Injecting excess fuel for raising more loads Supplying compressed air to remove combustion products fully Supplying the intake of an engine with air at a density greater than the density of the surrounding atmosphere ANSWER DOWNLOAD EXAMIANS APP
