Question

The velocity of the engine exhaust flow is a function of the temperature of the exhaust gas.

(a) True

(b) False

I have been asked this question by my school principal while I was bunking the class.

I'm obligated to ask this question of Thrust Producing Power Plant topic in section Aircraft Force Systems and the Equations of Motion of Aircraft Performance

Answer 1

Correct option is (a) True

Explanation: The velocity of the engine exhaust flow is a function of the temperature of the exhaust gas and this can be determined by the throttle setting. For any given engine thrust setting the exhaust gas velocity can be considered constant.
