Answer to Question #79147 in Molecular Physics | Thermodynamics for 1..

Question

A centrifugal compressor which represents an open system takes in air at a pressure
of 2 bar and a temperature of 28 °C at the rate of 1. 4 m 3 s −1. Compression takes
place according to the law PV 1.3 = C and the delivery pressure is 3.5 bar. The characteristic gas constant for the mixture is 287 J kg −1 K −1 and its specific heat
capacity at constant pressure is 1005 J kg −1 K −1 Determine:
(i) the input power and (ii) the heat transfer rate.
