Answer to Question #50425 in Engineering for mark

Question

given theses data

mass flow rate of air = 3kg/s
pressure at entry 0.96 bar pressure at exit = 8.6bar

temperature at entry = 290 k at exit 542.6 k
the rate of heat lost from the compressor = 8kw
the polytropic index = 1.4 and cp 1005j/kg.k

what are the power requirements of the compressor in Kw??

the specific emthaply at entry of turbine is 3MJ/kg and exit 1MJ/k. assuming that change in KE AND PE is neligible find the power in kw.??? (also using the data above if needed)

determine nett power in MW?? (using above data)

it will be much appreciated.
