A multistage axial compressor, with an overall isentropic efficiency of 0.83, is used to compress air at a stagnation temperature of 300 K through a pressure ratio of 10:1. Each stage of the compressor is similar, and the stagnation temperature rise across each compressor stage is 20 K. Assume Cp = 1005 J/kg K and γ = 1.4 for air. How many stages are there in the compressor?
A
17
B
13
C
19
D
11

Correct : a
