Question

Characteristic velocity of a rocket engine is equal to

• A. twice the discharge coefficient
• B. square root of discharge coefficient
• C. inverse of the discharge coefficient
• D. thrust of the rocket divided by initial mass of rocket

Hint:

Characteristic velocity is a fundamental parameter in assessing rocket engine performance, especially in relation to the rocket's overall mass efficiency.

Answer 1

The Correct Option is D

Step 1: Define Characteristic Velocity.
The characteristic velocity of a rocket engine is not directly defined by the discharge coefficient but is a measure of the rocket's ability to produce thrust relative to its mass, effectively describing the exhaust velocity of the propellant gases when corrected for the flow rate and throat area.
