Question
![10.8 An axial flow compressor with 50% degree of reaction is to have an overall com-
pression ratio of seven. The inlet and exit blade angles are 50° and 15°, both mea-
sured with respect to the axial direction. The inlet static temperature is 25°C and
the axial velocity can be assumed to be a constant at 160 m/s. If the isentropic
efficiency of the compressor is 0.88, estimate the stagnation temperature rise and
the number of stages required to achieve the desired compression ratio.
Ans: Aro=34.4°; Eight stages](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Feddb891f-e372-4750-8c2c-984e0972db8e%2F7a42e6ca-314b-48b2-bb69-b3780907ede8%2Fvixba1j_processed.png&w=3840&q=75)
