For a jet-propulsion unit, ideally the compressor work and turbine work are

(a) equal (b) unequal

(c) not related to each other (d) unpredictable.

The greater the difference between jet velocity and airplane velocity

(a) the greater the propulsive efficiency

(b) the less the propulsive efficiency

(c) the propulsive efficiency is

(d) none of the above. Unaffected
