A multistage axial compressor takes in air at 1 atm, 300 K and compresses it to a
minimum of 5 atm.
The mean blade speed is 245 m/s and work coefficient,
∆ഇ
is 0.55 for each stage.
For air, use C =1005 J/(kg-K), R = 287 J/(kg-K) and γ = 1.4.
If the compression is isentropic, the number of stages required is ___________
(rounded off to the next higher integer).
