Aerospace Engineering > GATE 2022 > Axial Compressors
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 the work coefficient, ΔCθ/U, is 0.55 for each stage. For air, use Cp = 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)
Correct : 6 or greater than 6
