Question Statement:
Which of the following statements is/are TRUE for a single stage axial compressor?
Options:
- (A) Starting from design condition and keeping the mass flow rate constant, if the blade RPM is increased, the compressor rotor may experience positive incidence flow separation (actual relative flow angle greater than the design blade angle)
- (B) Starting from design condition at the same blade RPM , if the mass flow rate is increased, the compressor rotor may experience positive incidence flow separation (actual relative flow angle greater than the design blade angle)
- (C) Keeping the mass flow rate constant, if the blade RPM is increased, the compressor may experience surge
- (D) At the same blade RPM, if the mass flow rate is increased, the compressor may experience surge
