Question:-
If n is the polytrophic index of compression and p2/p1 is the pressure ratio for a three-stage compressor with ideal inter-cooling, the expression for total work of three stage is
Option (A)
Option (B)
Option(C)
Option(D)
Correct Option:
(D)
Question Solution:
For ‘N’ stage
W = N. {n/(n-1)}.P1V1{(P2/P1)(n-1)/Nn - 1}
When N = 3
\ W = {3n / (n-1)}P1V1[(P2/P1)(n-1)/3n - 1]
