1.	Which of the following is correct?(a) Compressor consumes work produced by turbine(b) Compressor produces work to drive shaft(c) Compressor increases velocity of the flow(d) Lift is always same as weightThe question was asked at a job interview.My doubt is from Propulsion Selection topic in division Propulsion and Fuel System Integration of Aircraft Design
Answer» Correct answer is (a) Compressor consumes WORK produced by TURBINE To explain I would SAY: Turbine generates work to drive the shaft. This work is consumed to drive compressor. Compressor doesn’t produce work. Lift is not always same as weight. Compressor is used to increase pressure and temperature.
