None of the above

Correct Answer : True

Explanation : The integral form of conservative equation finds use in many practical scenarios such as finding thrust of a jet propulsion device – engine. It can be used to find out the thrust of turbojet, turboprop, ramjet, turbofan, rocket engine and many more.

None of the above

Correct Answer : Option (A) : True

Integral form of momentum equation cannot replace the need for theoretical and experimental measurements.

True

False

Can Not Say

None of the above

Correct Answer : Option (B) : False

Explanation : In real life scenario, computing the thrust of the jet engine using theoretical and experimental results can be very exhaustive. The data obtained is not just extensive but also complex. Thus, to replace this, an integral form of momentum equation is used which gives the result much more accurately.
