Tutorial $03-$ Centrifugal Compressors

Problem $01$

$1\mathrm{.}1$ A centrifugal compressor compresses from $1$ bar at $15C$ to $2\mathrm{.}15$ bar at

$95C.$ The mass of air delivered is $2\mathrm{.}2k\frac{g}{sec}.$ No heat is exchanged

between air and external sources during compression. Find the

compression efficiency without ideal adiabatic compression and

estimate the power absorbed$.$ Also, the change in entropy of air during

compression was found.
