If V₁ is the jet velocity and V₀ is the vehicle velocity, then propulsive efficiency of a turbojet engine is

A. $$\frac{{{{\text{V}}_1}}}{{{{\text{V}}_0} + {{\text{V}}_1}}}$$

B. $$\frac{{{{\text{V}}_0}}}{{{{\text{V}}_0} + {{\text{V}}_1}}}$$

C. $$\frac{{2{{\text{V}}_0}}}{{{{\text{V}}_0} + {{\text{V}}_1}}}$$

D. $$\frac{{2{{\text{V}}_1}}}{{{{\text{V}}_0} + {{\text{V}}_1}}}$$

Answer: Option C

Solution(By Examveda Team)

If V₁ is the jet velocity and V₀ is the vehicle velocity, then propulsive efficiency of a turbojet engine is $$\frac{{2{{\text{V}}_0}}}{{{{\text{V}}_0} + {{\text{V}}_1}}}$$
