An ideal Brayton refrigeration cycle has a compressor pressure ratio of 7. At the compressor inlet, the pressure and temperature of the entering air are 22 lbf/in.2 and 450°R, respectively. The temperature at the inlet of the turbine is 680°R. The compressor and turbine have esentropic efficiencies of 75% and 0.89%, respectively. For a refrigerating capacity of 16.5 tons, determine: (a) the mass flow rate of the refrigerant, in lb/min. (b) the net power input, in Btu/min. (c) the coefficient of performance.

Transcribed Image Text:An ideal Brayton refrigeration cycle has a
compressor pressure ratio of 7. At the
compressor inlet, the pressure and
temperature of the entering air are 22 lbf/in.2
and 450°R, respectively. The temperature at
the inlet of the turbine is 680°R. The
compressor and turbine have esentropic
efficiencies of 75% and 0.89%, respectively.
For a refrigerating capacity of 16.5 tons,
determine:
(a) the mass flow rate of the refrigerant, in
lb/min.
(b) the net power input, in Btu/min.
(c) the coefficient of performance.
(d) the rate of entropy production in the
compressor, in Btu/min. R.
(e) the rate of entropy production in the
turbine, in Btu/min. R.
