Internal Combustion Engines The compensating jet in a carburettor supplies almost constant amount of petrol at all speeds because the Flow is produced due to the static head in the float chamber The diameter of the jet is constant and the discharge coefficient is invariant The flow from the main jet is diverted to the compensating jet with increase in speed Jet area is automatically varied depending on the suction Flow is produced due to the static head in the float chamber The diameter of the jet is constant and the discharge coefficient is invariant The flow from the main jet is diverted to the compensating jet with increase in speed Jet area is automatically varied depending on the suction ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines If V₁ is the jet velocity and V₀ is the vehicle velocity, then the propulsive efficiency of a rocket is given by V₁/(V₀ + V₁) (V₀/V₁)/ [1 + (V₀/V₁)²] V₀/(V₀ + V₁) [2(V₀/V₁)]/ [1 + (V₀/V₁)²] V₁/(V₀ + V₁) (V₀/V₁)/ [1 + (V₀/V₁)²] V₀/(V₀ + V₁) [2(V₀/V₁)]/ [1 + (V₀/V₁)²] ANSWER DOWNLOAD EXAMIANS APP
